Install

Rclone is a Go program and comes as a single binary file.

Download the relevant binary.

Or alternatively if you have Go 1.5+ installed use

go get github.com/ncw/rclone

and this will build the binary in $GOPATH/bin. If you have built rclone before then you will want to update its dependencies first with this

go get -u -v github.com/ncw/rclone/...

See the Usage section of the docs for how to use rclone, or run rclone -h.

linux binary downloaded files install example

unzip rclone-v1.17-linux-amd64.zip
cd rclone-v1.17-linux-amd64
#copy binary file
sudo cp rclone /usr/sbin/
sudo chown root:root /usr/sbin/rclone
sudo chmod 755 /usr/sbin/rclone
#install manpage
sudo mkdir -p /usr/local/share/man/man1
sudo cp rclone.1 /usr/local/share/man/man1/
sudo mandb

Installation with Ansible

This can be done with Stefan Weichinger's ansible role.

Instructions

git clone https://github.com/stefangweichinger/ansible-rclone.git into your local roles-directory
add the role to the hosts you want rclone installed to:

    - hosts: rclone-hosts
      roles:
          - rclone

Configure

First you'll need to configure rclone. As the object storage systems have quite complicated authentication these are kept in a config file .rclone.conf in your home directory by default. (You can use the --config option to choose a different config file.)

The easiest way to make the config is to run rclone with the config option:

rclone config

See the following for detailed instructions for

Usage

Rclone syncs a directory tree from one storage system to another.

Its syntax is like this

Syntax: [options] subcommand <parameters> <parameters...>

Source and destination paths are specified by the name you gave the storage system in the config file then the sub path, eg "drive:myfolder" to look at "myfolder" in Google drive.

You can define as many storage paths as you like in the config file.

Subcommands

rclone uses a system of subcommands. For example

rclone ls remote:path # lists a re
rclone copy /local/path remote:path # copies /local/path to the remote
rclone sync /local/path remote:path # syncs /local/path to the remote

rclone config

rclone copy

Copy files from source to dest, skipping already copied

Synopsis

Copy the source to the destination. Doesn't transfer unchanged files, testing by size and modification time or MD5SUM. Doesn't delete files from the destination.

Note that it is always the contents of the directory that is synced, not the directory so when source:path is a directory, it's the contents of source:path that are copied, not the directory name and contents.

If dest:path doesn't exist, it is created and the source:path contents go there.

For example

rclone copy source:sourcepath dest:destpath

Let's say there are two files in sourcepath

sourcepath/one.txt
sourcepath/two.txt

This copies them to

destpath/one.txt
destpath/two.txt

Not to

destpath/sourcepath/one.txt
destpath/sourcepath/two.txt

If you are familiar with rsync, rclone always works as if you had written a trailing / - meaning "copy the contents of this directory". This applies to all commands and whether you are talking about the source or destination.

See the --no-traverse option for controlling whether rclone lists the destination directory or not.

rclone copy source:path dest:path

rclone sync

Make source and dest identical, modifying destination only.

Synopsis

Sync the source to the destination, changing the destination only. Doesn't transfer unchanged files, testing by size and modification time or MD5SUM. Destination is updated to match source, including deleting files if necessary.

Important: Since this can cause data loss, test first with the --dry-run flag to see exactly what would be copied and deleted.

Note that files in the destination won't be deleted if there were any errors at any point.

It is always the contents of the directory that is synced, not the directory so when source:path is a directory, it's the contents of source:path that are copied, not the directory name and contents. See extended explanation in the copy command above if unsure.

If dest:path doesn't exist, it is created and the source:path contents go there.

rclone sync source:path dest:path

rclone move

Move files from source to dest.

Synopsis

Moves the contents of the source directory to the destination directory. Rclone will error if the source and destination overlap.

If no filters are in use and if possible this will server side move source:path into dest:path. After this source:path will no longer longer exist.

Otherwise for each file in source:path selected by the filters (if any) this will move it into dest:path. If possible a server side move will be used, otherwise it will copy it (server side if possible) into dest:path then delete the original (if no errors on copy) in source:path.

Important: Since this can cause data loss, test first with the --dry-run flag.

rclone move source:path dest:path

rclone delete

Remove the contents of path.

Synopsis

Remove the contents of path. Unlike purge it obeys include/exclude filters so can be used to selectively delete files.

Eg delete all files bigger than 100MBytes

Check what would be deleted first (use either)

rclone --min-size 100M lsl remote:path
rclone --dry-run --min-size 100M delete remote:path

Then delete

rclone --min-size 100M delete remote:path

That reads "delete everything with a minimum size of 100 MB", hence delete all files bigger than 100MBytes.

rclone delete remote:path

rclone purge

Remove the path and all of its contents.

Synopsis

Remove the path and all of its contents. Note that this does not obey include/exclude filters - everything will be removed. Use delete if you want to selectively delete files.

rclone purge remote:path

rclone mkdir

Make the path if it doesn't already exist.

Synopsis

Make the path if it doesn't already exist.

rclone mkdir remote:path

rclone rmdir

Remove the path if empty.

Synopsis

Remove the path. Note that you can't remove a path with objects in it, use purge for that.

rclone rmdir remote:path

rclone check

Checks the files in the source and destination match.

Synopsis

Checks the files in the source and destination match. It compares sizes and MD5SUMs and prints a report of files which don't match. It doesn't alter the source or destination.

--size-only may be used to only compare the sizes, not the MD5SUMs.

rclone check source:path dest:path

rclone ls

List all the objects in the the path with size and path.

Synopsis

List all the objects in the the path with size and path.

rclone ls remote:path

rclone lsd

List all directories/containers/buckets in the the path.

Synopsis

List all directories/containers/buckets in the the path.

rclone lsd remote:path

rclone lsl

List all the objects path with modification time, size and path.

Synopsis

List all the objects path with modification time, size and path.

rclone lsl remote:path

rclone md5sum

Produces an md5sum file for all the objects in the path.

Synopsis

Produces an md5sum file for all the objects in the path. This is in the same format as the standard md5sum tool produces.

rclone md5sum remote:path

rclone sha1sum

Produces an sha1sum file for all the objects in the path.

Synopsis

Produces an sha1sum file for all the objects in the path. This is in the same format as the standard sha1sum tool produces.

rclone sha1sum remote:path

rclone size

Prints the total size and number of objects in remote:path.

Synopsis

Prints the total size and number of objects in remote:path.

rclone size remote:path

rclone version

Show the version number.

Synopsis

Show the version number.

rclone version

rclone cleanup

Clean up the remote if possible

Synopsis

Clean up the remote if possible. Empty the trash or delete old file versions. Not supported by all remotes.

rclone cleanup remote:path

rclone dedupe

Interactively find duplicate files delete/rename them.

Synopsis

By default dedup interactively finds duplicate files and offers to delete all but one or rename them to be different. Only useful with Google Drive which can have duplicate file names.

The dedupe command will delete all but one of any identical (same md5sum) files it finds without confirmation. This means that for most duplicated files the dedupe command will not be interactive. You can use --dry-run to see what would happen without doing anything.

Here is an example run.

Before - with duplicates

$ rclone lsl drive:dupes
  6048320 2016-03-05 16:23:16.798000000 one.txt
  6048320 2016-03-05 16:23:11.775000000 one.txt

   564374 2016-03-05 16:22:52.118000000 two.txt

Now the dedupe session

Dedupe can be run non interactively using the --dedupe-mode flag or by using an extra parameter with the same value

--dedupe-mode interactive - interactive as above.
--dedupe-mode skip - removes identical files then skips anything left.
--dedupe-mode first - removes identical files then keeps the first one.
--dedupe-mode newest - removes identical files then keeps the newest one.
--dedupe-mode oldest - removes identical files then keeps the oldest one.
--dedupe-mode rename - removes identical files then renames the rest to be different.

For example to rename all the identically named photos in your Google Photos directory, do

rclone dedupe --dedupe-mode rename "drive:Google Photos"

rclone dedupe rename "drive:Google Photos"

rclone dedupe [mode] remote:path

Options

      --dedupe-mode string   Dedupe mode interactive|skip|first|newest|oldest|rename.

rclone authorize

Remote authorization.

Synopsis

Remote authorization. Used to authorize a remote or headless rclone from a machine with a browser - use as instructed by rclone config.

rclone authorize

rclone cat

Concatenates any files and sends them to stdout.

Synopsis

rclone cat sends any files to standard output.

You can use it like this to output a single file

rclone cat remote:path/to/file

Or like this to output any file in dir or subdirectories.

rclone cat remote:path/to/dir

Or like this to output any .txt files in dir or subdirectories.

rclone --include "*.txt" cat remote:path/to/dir

rclone cat remote:path

rclone genautocomplete

Output bash completion script for rclone.

Synopsis

Generates a bash shell autocompletion script for rclone.

This writes to /etc/bash_completion.d/rclone by default so will probably need to be run with sudo or as root, eg

sudo rclone genautocomplete

Logout and login again to use the autocompletion scripts, or source them directly

. /etc/bash_completion

If you supply a command line argument the script will be written there.

rclone genautocomplete [output_file]

rclone gendocs

Output markdown docs for rclone to the directory supplied.

Synopsis

This produces markdown docs for the rclone commands to the directory supplied. These are in a format suitable for hugo to render into the rclone.org website.

rclone gendocs output_directory

rclone mount

Mount the remote as a mountpoint. EXPERIMENTAL

Synopsis

rclone mount allows Linux, FreeBSD and macOS to mount any of Rclone's cloud storage systems as a file system with FUSE.

This is EXPERIMENTAL - use with care.

First set up your remote using rclone config. Check it works with rclone ls etc.

Start the mount like this

rclone mount remote:path/to/files /path/to/local/mount &

Stop the mount with

fusermount -u /path/to/local/mount

Or with OS X

umount -u /path/to/local/mount

Limitations

This can only read files seqentially, or write files sequentially. It can't read and write or seek in files.

rclonefs inherits rclone's directory handling. In rclone's world directories don't really exist. This means that empty directories will have a tendency to disappear once they fall out of the directory cache.

The bucket based FSes (eg swift, s3, google compute storage, b2) won't work from the root - you will need to specify a bucket, or a path within the bucket. So swift: won't work whereas swift:bucket will as will swift:bucket/path.

Only supported on Linux, FreeBSD and OS X at the moment.

rclone mount vs rclone sync/copy

File systems expect things to be 100% reliable, whereas cloud storage systems are a long way from 100% reliable. The rclone sync/copy commands cope with this with lots of retries. However rclone mount can't use retries in the same way without making local copies of the uploads. This might happen in the future, but for the moment rclone mount won't do that, so will be less reliable than the rclone command.

Bugs

All the remotes should work for read, but some may not for write
- those which need to know the size in advance won't - eg B2
- maybe should pass in size as -1 to mean work it out

TODO

Check hashes on upload/download
Preserve timestamps
Move directories

rclone mount remote:path /path/to/mountpoint

Options

      --debug-fuse   Debug the FUSE internals - needs -v.
      --no-modtime   Don't read the modification time (can speed things up).

Copying single files

rclone normally syncs or copies directories. However if the source remote points to a file, rclone will just copy that file. The destination remote must point to a directory - rclone will give the error Failed to create file system for "remote:file": is a file not a directory if it isn't.

For example, suppose you have a remote with a file in called test.jpg, then you could copy just that file like this

rclone copy remote:test.jpg /tmp/download

The file test.jpg will be placed inside /tmp/download.

This is equivalent to specifying

rclone copy --no-traverse --files-from /tmp/files remote: /tmp/download

Where /tmp/files contains the single line

test.jpg

It is recommended to use copy when copying single files not sync. They have pretty much the same effect but copy will use a lot less memory.

Quoting and the shell

When you are typing commands to your computer you are using something called the command line shell. This interprets various characters in an OS specific way.

Here are some gotchas which may help users unfamiliar with the shell rules

Linux / OSX

If your names have spaces or shell metacharacters (eg *, ?, $, ', " etc) then you must quote them. Use single quotes ' by default.

rclone copy 'Important files?' remote:backup

If you want to send a ' you will need to use ", eg

rclone copy "O'Reilly Reviews" remote:backup

The rules for quoting metacharacters are complicated and if you want the full details you'll have to consult the manual page for your shell.

Windows

If your names have spaces in you need to put them in ", eg

rclone copy "E:\folder name\folder name\folder name" remote:backup

If you are using the root directory on its own then don't quote it (see #464 for why), eg

rclone copy E:\ remote:backup

Server Side Copy

Drive, S3, Dropbox, Swift and Google Cloud Storage support server side copy.

This means if you want to copy one folder to another then rclone won't download all the files and re-upload them; it will instruct the server to copy them in place.

rclone copy s3:oldbucket s3:newbucket

Will copy the contents of oldbucket to newbucket without downloading and re-uploading.

Remotes which don't support server side copy (eg local) will download and re-upload in this case.

Server side copies are used with sync and copy and will be identified in the log when using the -v flag.

Server side copies will only be attempted if the remote names are the same.

This can be used when scripting to make aged backups efficiently, eg

rclone sync remote:current-backup remote:previous-backup
rclone sync /path/to/files remote:current-backup

Options

Rclone has a number of options to control its behaviour.

Options which use TIME use the go time parser. A duration string is a possibly signed sequence of decimal numbers, each with optional fraction and a unit suffix, such as "300ms", "-1.5h" or "2h45m". Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".

Options which use SIZE use kByte by default. However a suffix of b for bytes, k for kBytes, M for MBytes and G for GBytes may be used. These are the binary units, eg 1, 2**10, 2**20, 2**30 respectively.

--bwlimit=SIZE

Bandwidth limit in kBytes/s, or use suffix b|k|M|G. The default is 0 which means to not limit bandwidth.

For example to limit bandwidth usage to 10 MBytes/s use --bwlimit 10M

This only limits the bandwidth of the data transfer, it doesn't limit the bandwith of the directory listings etc.

--checkers=N

The number of checkers to run in parallel. Checkers do the equality checking of files during a sync. For some storage systems (eg s3, swift, dropbox) this can take a significant amount of time so they are run in parallel.

The default is to run 8 checkers in parallel.

-c, --checksum

Normally rclone will look at modification time and size of files to see if they are equal. If you set this flag then rclone will check the file hash and size to determine if files are equal.

This is useful when the remote doesn't support setting modified time and a more accurate sync is desired than just checking the file size.

This is very useful when transferring between remotes which store the same hash type on the object, eg Drive and Swift. For details of which remotes support which hash type see the table in the overview section.

Eg rclone --checksum sync s3:/bucket swift:/bucket would run much quicker than without the --checksum flag.

When using this flag, rclone won't update mtimes of remote files if they are incorrect as it would normally.

--config=CONFIG_FILE

Specify the location of the rclone config file. Normally this is in your home directory as a file called .rclone.conf. If you run rclone -h and look at the help for the --config option you will see where the default location is for you. Use this flag to override the config location, eg rclone --config=".myconfig" .config.

--contimeout=TIME

Set the connection timeout. This should be in go time format which looks like 5s for 5 seconds, 10m for 10 minutes, or 3h30m.

The connection timeout is the amount of time rclone will wait for a connection to go through to a remote object storage system. It is 1m by default.

--dedupe-mode MODE

Mode to run dedupe command in. One of interactive, skip, first, newest, oldest, rename. The default is interactive. See the dedupe command for more information as to what these options mean.

-n, --dry-run

Do a trial run with no permanent changes. Use this to see what rclone would do without actually doing it. Useful when setting up the sync command which deletes files in the destination.

--ignore-existing

Using this option will make rclone unconditionally skip all files that exist on the destination, no matter the content of these files.

While this isn't a generally recommended option, it can be useful in cases where your files change due to encryption. However, it cannot correct partial transfers in case a transfer was interrupted.

--ignore-size

Normally rclone will look at modification time and size of files to see if they are equal. If you set this flag then rclone will check only the modification time. If --checksum is set then it only checks the checksum.

It will also cause rclone to skip verifying the sizes are the same after transfer.

This can be useful for transferring files to and from onedrive which occasionally misreports the size of image files (see #399 for more info).

-I, --ignore-times

Using this option will cause rclone to unconditionally upload all files regardless of the state of files on the destination.

Normally rclone would skip any files that have the same modification time and are the same size (or have the same checksum if using --checksum).

--log-file=FILE

Log all of rclone's output to FILE. This is not active by default. This can be useful for tracking down problems with syncs in combination with the -v flag. See the Logging section for more info.

--low-level-retries NUMBER

This controls the number of low level retries rclone does.

A low level retry is used to retry a failing operation - typically one HTTP request. This might be uploading a chunk of a big file for example. You will see low level retries in the log with the -v flag.

This shouldn't need to be changed from the default in normal operations, however if you get a lot of low level retries you may wish to reduce the value so rclone moves on to a high level retry (see the --retries flag) quicker.

Disable low level retries with --low-level-retries 1.

--max-depth=N

This modifies the recursion depth for all the commands except purge.

So if you do rclone --max-depth 1 ls remote:path you will see only the files in the top level directory. Using --max-depth 2 means you will see all the files in first two directory levels and so on.

For historical reasons the lsd command defaults to using a --max-depth of 1 - you can override this with the command line flag.

You can use this command to disable recursion (with --max-depth 1).

Note that if you use this with sync and --delete-excluded the files not recursed through are considered excluded and will be deleted on the destination. Test first with --dry-run if you are not sure what will happen.

--modify-window=TIME

When checking whether a file has been modified, this is the maximum allowed time difference that a file can have and still be considered equivalent.

The default is 1ns unless this is overridden by a remote. For example OS X only stores modification times to the nearest second so if you are reading and writing to an OS X filing system this will be 1s by default.

This command line flag allows you to override that computed default.

--no-gzip-encoding

Don't set Accept-Encoding: gzip. This means that rclone won't ask the server for compressed files automatically. Useful if you've set the server to return files with Content-Encoding: gzip but you uploaded compressed files.

There is no need to set this in normal operation, and doing so will decrease the network transfer efficiency of rclone.

--no-update-modtime

When using this flag, rclone won't update modification times of remote files if they are incorrect as it would normally.

This can be used if the remote is being synced with another tool also (eg the Google Drive client).

-q, --quiet

Normally rclone outputs stats and a completion message. If you set this flag it will make as little output as possible.

--retries int

Retry the entire sync if it fails this many times it fails (default 3).

Some remotes can be unreliable and a few retries helps pick up the files which didn't get transferred because of errors.

Disable retries with --retries 1.

--size-only

Normally rclone will look at modification time and size of files to see if they are equal. If you set this flag then rclone will check only the size.

This can be useful transferring files from dropbox which have been modified by the desktop sync client which doesn't set checksums of modification times in the same way as rclone.

--stats=TIME

Rclone will print stats at regular intervals to show its progress.

This sets the interval.

The default is 1m. Use 0 to disable.

--delete-(before,during,after)

This option allows you to specify when files on your destination are deleted when you sync folders.

Specifying the value --delete-before will delete all files present on the destination, but not on the source before starting the transfer of any new or updated files. This uses extra memory as it has to store the source listing before proceeding.

Specifying --delete-during (default value) will delete files while checking and uploading files. This is usually the fastest option. Currently this works the same as --delete-after but it may change in the future.

Specifying --delete-after will delay deletion of files until all new/updated files have been successfully transfered.

--timeout=TIME

This sets the IO idle timeout. If a transfer has started but then becomes idle for this long it is considered broken and disconnected.

The default is 5m. Set to 0 to disable.

--transfers=N

The number of file transfers to run in parallel. It can sometimes be useful to set this to a smaller number if the remote is giving a lot of timeouts or bigger if you have lots of bandwidth and a fast remote.

The default is to run 4 file transfers in parallel.

-u, --update

This forces rclone to skip any files which exist on the destination and have a modified time that is newer than the source file.

If an existing destination file has a modification time equal (within the computed modify window precision) to the source file's, it will be updated if the sizes are different.

On remotes which don't support mod time directly the time checked will be the uploaded time. This means that if uploading to one of these remoes, rclone will skip any files which exist on the destination and have an uploaded time that is newer than the modification time of the source file.

This can be useful when transferring to a remote which doesn't support mod times directly as it is more accurate than a --size-only check and faster than using --checksum.

-v, --verbose

If you set this flag, rclone will become very verbose telling you about every file it considers and transfers.

Very useful for debugging.

-V, --version

Prints the version number

Configuration Encryption

Your configuration file contains information for logging in to your cloud services. This means that you should keep your .rclone.conf file in a secure location.

If you are in an environment where that isn't possible, you can add a password to your configuration. This means that you will have to enter the password every time you start rclone.

To add a password to your rclone configuration, execute rclone config.

>rclone config
Current remotes:

e) Edit existing remote
n) New remote
d) Delete remote
s) Set configuration password
q) Quit config
e/n/d/s/q>

Go into s, Set configuration password:

e/n/d/s/q> s
Your configuration is not encrypted.
If you add a password, you will protect your login information to cloud services.
a) Add Password
q) Quit to main menu
a/q> a
Enter NEW configuration password:
password:
Confirm NEW password:
password:
Password set
Your configuration is encrypted.
c) Change Password
u) Unencrypt configuration
q) Quit to main menu
c/u/q>

Your configuration is now encrypted, and every time you start rclone you will now be asked for the password. In the same menu you can change the password or completely remove encryption from your configuration.

There is no way to recover the configuration if you lose your password.

rclone uses nacl secretbox which in turn uses XSalsa20 and Poly1305 to encrypt and authenticate your configuration with secret-key cryptography. The password is SHA-256 hashed, which produces the key for secretbox. The hashed password is not stored.

While this provides very good security, we do not recommend storing your encrypted rclone configuration in public if it contains sensitive information, maybe except if you use a very strong password.

If it is safe in your environment, you can set the RCLONE_CONFIG_PASS environment variable to contain your password, in which case it will be used for decrypting the configuration.

If you are running rclone inside a script, you might want to disable password prompts. To do that, pass the parameter --ask-password=false to rclone. This will make rclone fail instead of asking for a password if RCLONE_CONFIG_PASS doesn't contain a valid password.

Developer options

These options are useful when developing or debugging rclone. There are also some more remote specific options which aren't documented here which are used for testing. These start with remote name eg --drive-test-option - see the docs for the remote in question.

--cpuprofile=FILE

Write CPU profile to file. This can be analysed with go tool pprof.

--dump-bodies

Dump HTTP headers and bodies - may contain sensitive info. Can be very verbose. Useful for debugging only.

--dump-filters

Dump the filters to the output. Useful to see exactly what include and exclude options are filtering on.

--dump-headers

Dump HTTP headers - may contain sensitive info. Can be very verbose. Useful for debugging only.

--memprofile=FILE

Write memory profile to file. This can be analysed with go tool pprof.

--no-check-certificate=true/false

--no-check-certificate controls whether a client verifies the server's certificate chain and host name. If --no-check-certificate is true, TLS accepts any certificate presented by the server and any host name in that certificate. In this mode, TLS is susceptible to man-in-the-middle attacks.

This option defaults to false.

This should be used only for testing.

--no-traverse

The --no-traverse flag controls whether the destination file system is traversed when using the copy or move commands.

If you are only copying a small number of files and/or have a large number of files on the destination then --no-traverse will stop rclone listing the destination and save time.

However if you are copying a large number of files, escpecially if you are doing a copy where lots of the files haven't changed and won't need copying then you shouldn't use --no-traverse.

It can also be used to reduce the memory usage of rclone when copying

rclone --no-traverse copy src dst won't load either the source or destination listings into memory so will use the minimum amount of memory.

Filtering

For the filtering options

--delete-excluded
--filter
--filter-from
--exclude
--exclude-from
--include
--include-from
--files-from
--min-size
--max-size
--min-age
--max-age
--dump-filters

See the filtering section.

Logging

rclone has 3 levels of logging, Error, Info and Debug.

By default rclone logs Error and Info to standard error and Debug to standard output. This means you can redirect standard output and standard error to different places.

By default rclone will produce Error and Info level messages.

If you use the -q flag, rclone will only produce Error messages.

If you use the -v flag, rclone will produce Error, Info and Debug messages.

If you use the --log-file=FILE option, rclone will redirect Error, Info and Debug messages along with standard error to FILE.

Exit Code

If any errors occurred during the command, rclone will set a non zero exit code. This allows scripts to detect when rclone operations have failed.

Configuring rclone on a remote / headless machine

Some of the configurations (those involving oauth2) require an Internet connected web browser.

If you are trying to set rclone up on a remote or headless box with no browser available on it (eg a NAS or a server in a datacenter) then you will need to use an alternative means of configuration. There are two ways of doing it, described below.

Configuring using rclone authorize

On the headless box

...
Remote config
Use auto config?
 * Say Y if not sure
 * Say N if you are working on a remote or headless machine
y) Yes
n) No
y/n> n
For this to work, you will need rclone available on a machine that has a web browser available.
Execute the following on your machine:
	rclone authorize "amazon cloud drive"
Then paste the result below:
result>

Then on your main desktop machine

rclone authorize "amazon cloud drive"
If your browser doesn't open automatically go to the following link: http://127.0.0.1:53682/auth
Log in and authorize rclone for access
Waiting for code...
Got code
Paste the following into your remote machine --->
SECRET_TOKEN
<---End paste

Then back to the headless box, paste in the code

result> SECRET_TOKEN
--------------------
[acd12]
client_id = 
client_secret = 
token = SECRET_TOKEN
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d>

Configuring by copying the config file

Rclone stores all of its config in a single configuration file. This can easily be copied to configure a remote rclone.

So first configure rclone on your desktop machine

rclone config

to set up the config file.

Find the config file by running rclone -h and looking for the help for the --config option

$ rclone -h
[snip]
      --config="/home/user/.rclone.conf": Config file.
[snip]

Now transfer it to the remote box (scp, cut paste, ftp, sftp etc) and place it in the correct place (use rclone -h on the remote box to find out where).

Filtering, includes and excludes

Rclone has a sophisticated set of include and exclude rules. Some of these are based on patterns and some on other things like file size.

The filters are applied for the copy, sync, move, ls, lsl, md5sum, sha1sum, size, delete and check operations. Note that purge does not obey the filters.

Each path as it passes through rclone is matched against the include and exclude rules like --include, --exclude, --include-from, --exclude-from, --filter, or --filter-from. The simplest way to try them out is using the ls command, or --dry-run together with -v.

Important Due to limitations of the command line parser you can only use any of these options once - if you duplicate them then rclone will use the last one only.

Patterns

The patterns used to match files for inclusion or exclusion are based on "file globs" as used by the unix shell.

If the pattern starts with a / then it only matches at the top level of the directory tree, relative to the root of the remote. If it doesn't start with / then it is matched starting at the end of the path, but it will only match a complete path element:

file.jpg  - matches "file.jpg"
          - matches "directory/file.jpg"
          - doesn't match "afile.jpg"
          - doesn't match "directory/afile.jpg"
/file.jpg - matches "file.jpg" in the root directory of the remote
          - doesn't match "afile.jpg"
          - doesn't match "directory/file.jpg"

Important Note that you must use / in patterns and not \ even if running on Windows.

A * matches anything but not a /.

*.jpg  - matches "file.jpg"
       - matches "directory/file.jpg"
       - doesn't match "file.jpg/something"

Use ** to match anything, including slashes (/).

dir/** - matches "dir/file.jpg"
       - matches "dir/dir1/dir2/file.jpg"
       - doesn't match "directory/file.jpg"
       - doesn't match "adir/file.jpg"

A ? matches any character except a slash /.

l?ss  - matches "less"
      - matches "lass"
      - doesn't match "floss"

A [ and ] together make a a character class, such as [a-z] or [aeiou] or [[:alpha:]]. See the go regexp docs for more info on these.

h[ae]llo - matches "hello"
         - matches "hallo"
         - doesn't match "hullo"

A { and } define a choice between elements. It should contain a comma seperated list of patterns, any of which might match. These patterns can contain wildcards.

{one,two}_potato - matches "one_potato"
                 - matches "two_potato"
                 - doesn't match "three_potato"
                 - doesn't match "_potato"

Special characters can be escaped with a \ before them.

\*.jpg       - matches "*.jpg"
\\.jpg       - matches "\.jpg"
\[one\].jpg  - matches "[one].jpg"

Note also that rclone filter globs can only be used in one of the filter command line flags, not in the specification of the remote, so rclone copy "remote:dir*.jpg" /path/to/dir won't work - what is required is rclone --include "*.jpg" copy remote:dir /path/to/dir

Directories

Rclone keeps track of directories that could match any file patterns.

Eg if you add the include rule

\a\*.jpg

Rclone will synthesize the directory include rule

\a\

If you put any rules which end in \ then it will only match directories.

Directory matches are only used to optimise directory access patterns - you must still match the files that you want to match. Directory matches won't optimise anything on bucket based remotes (eg s3, swift, google compute storage, b2) which don't have a concept of directory.

Differences between rsync and rclone patterns

Rclone implements bash style {a,b,c} glob matching which rsync doesn't.

Rclone always does a wildcard match so \ must always escape a \.

How the rules are used

Rclone maintains a list of include rules and exclude rules.

Each file is matched in order against the list until it finds a match. The file is then included or excluded according to the rule type.

If the matcher falls off the bottom of the list then the path is included.

For example given the following rules, + being include, - being exclude,

- secret*.jpg
+ *.jpg
+ *.png
+ file2.avi
- *

This would include

file1.jpg
file3.png
file2.avi

This would exclude

secret17.jpg
non *.jpg and *.png

A similar process is done on directory entries before recursing into them. This only works on remotes which have a concept of directory (Eg local, google drive, onedrive, amazon drive) and not on bucket based remotes (eg s3, swift, google compute storage, b2).

Adding filtering rules

Filtering rules are added with the following command line flags.

`--exclude` - Exclude files matching pattern

Add a single exclude rule with --exclude.

Eg --exclude *.bak to exclude all bak files from the sync.

`--exclude-from` - Read exclude patterns from file

Add exclude rules from a file.

Prepare a file like this exclude-file.txt

# a sample exclude rule file
*.bak
file2.jpg

Then use as --exclude-from exclude-file.txt. This will sync all files except those ending in bak and file2.jpg.

This is useful if you have a lot of rules.

`--include` - Include files matching pattern

Add a single include rule with --include.

Eg --include *.{png,jpg} to include all png and jpg files in the backup and no others.

This adds an implicit --exclude * at the very end of the filter list. This means you can mix --include and --include-from with the other filters (eg --exclude) but you must include all the files you want in the include statement. If this doesn't provide enough flexibility then you must use --filter-from.

`--include-from` - Read include patterns from file

Add include rules from a file.

Prepare a file like this include-file.txt

# a sample include rule file
*.jpg
*.png
file2.avi

Then use as --include-from include-file.txt. This will sync all jpg, png files and file2.avi.

This is useful if you have a lot of rules.

`--filter` - Add a file-filtering rule

This can be used to add a single include or exclude rule. Include rules start with + and exclude rules start with - . A special rule called ! can be used to clear the existing rules.

Eg --filter "- *.bak" to exclude all bak files from the sync.

`--filter-from` - Read filtering patterns from a file

Add include/exclude rules from a file.

Prepare a file like this filter-file.txt

# a sample exclude rule file
- secret*.jpg
+ *.jpg
+ *.png
+ file2.avi
# exclude everything else
- *

Then use as --filter-from filter-file.txt. The rules are processed in the order that they are defined.

This example will include all jpg and png files, exclude any files matching secret*.jpg and include file2.avi. Everything else will be excluded from the sync.

`--files-from` - Read list of source-file names

This reads a list of file names from the file passed in and only these files are transferred. The filtering rules are ignored completely if you use this option.

Prepare a file like this files-from.txt

# comment
file1.jpg
file2.jpg

Then use as --files-from files-from.txt. This will only transfer file1.jpg and file2.jpg providing they exist.

For example, let's say you had a few files you want to back up regularly with these absolute paths:

/home/user1/important
/home/user1/dir/file
/home/user2/stuff

To copy these you'd find a common subdirectory - in this case /home and put the remaining files in files-from.txt with or without leading /, eg

user1/important
user1/dir/file
user2/stuff

You could then copy these to a remote like this

rclone copy --files-from files-from.txt /home remote:backup

The 3 files will arrive in remote:backup with the paths as in the files-from.txt.

You could of course choose / as the root too in which case your files-from.txt might look like this.

/home/user1/important
/home/user1/dir/file
/home/user2/stuff

And you would transfer it like this

rclone copy --files-from files-from.txt / remote:backup

In this case there will be an extra home directory on the remote.

`--min-size` - Don't transfer any file smaller than this

This option controls the minimum size file which will be transferred. This defaults to kBytes but a suffix of k, M, or G can be used.

For example --min-size 50k means no files smaller than 50kByte will be transferred.

`--max-size` - Don't transfer any file larger than this

This option controls the maximum size file which will be transferred. This defaults to kBytes but a suffix of k, M, or G can be used.

For example --max-size 1G means no files larger than 1GByte will be transferred.

`--max-age` - Don't transfer any file older than this

This option controls the maximum age of files to transfer. Give in seconds or with a suffix of:

ms - Milliseconds
s - Seconds
m - Minutes
h - Hours
d - Days
w - Weeks
M - Months
y - Years

For example --max-age 2d means no files older than 2 days will be transferred.

`--min-age` - Don't transfer any file younger than this

This option controls the minimum age of files to transfer. Give in seconds or with a suffix (see --max-age for list of suffixes)

For example --min-age 2d means no files younger than 2 days will be transferred.

`--delete-excluded` - Delete files on dest excluded from sync

Important this flag is dangerous - use with --dry-run and -v first.

When doing rclone sync this will delete any files which are excluded from the sync on the destination.

If for example you did a sync from A to B without the --min-size 50k flag

rclone sync A: B:

Then you repeated it like this with the --delete-excluded

rclone --min-size 50k --delete-excluded sync A: B:

This would delete all files on B which are less than 50 kBytes as these are now excluded from the sync.

Always test first with --dry-run and -v before using this flag.

`--dump-filters` - dump the filters to the output

This dumps the defined filters to the output as regular expressions.

Useful for debugging.

Quoting shell metacharacters

The examples above may not work verbatim in your shell as they have shell metacharacters in them (eg *), and may require quoting.

Eg linux, OSX

--include \*.jpg
--include '*.jpg'
--include='*.jpg'

In Windows the expansion is done by the command not the shell so this should work fine

--include *.jpg

Overview of cloud storage systems

Each cloud storage system is slighly different. Rclone attempts to provide a unified interface to them, but some underlying differences show through.

Features

Here is an overview of the major features of each cloud storage system.

Name	Hash	ModTime	Case Insensitive	Duplicate Files
Google Drive	MD5	Yes	No	Yes
Amazon S3	MD5	Yes	No	No
Openstack Swift	MD5	Yes	No	No
Dropbox	-	No	Yes	No
Google Cloud Storage	MD5	Yes	No	No
Amazon Drive	MD5	No	Yes	No
Microsoft One Drive	SHA1	Yes	Yes	No
Hubic	MD5	Yes	No	No
Backblaze B2	SHA1	Yes	No	No
Yandex Disk	MD5	Yes	No	No
The local filesystem	All	Yes	Depends	No

Hash

The cloud storage system supports various hash types of the objects.
The hashes are used when transferring data as an integrity check and can be specifically used with the --checksum flag in syncs and in the check command.

To use the checksum checks between filesystems they must support a common hash type.

ModTime

The cloud storage system supports setting modification times on objects. If it does then this enables a using the modification times as part of the sync. If not then only the size will be checked by default, though the MD5SUM can be checked with the --checksum flag.

All cloud storage systems support some kind of date on the object and these will be set when transferring from the cloud storage system.

Case Insensitive

If a cloud storage systems is case sensitive then it is possible to have two files which differ only in case, eg file.txt and FILE.txt. If a cloud storage system is case insensitive then that isn't possible.

This can cause problems when syncing between a case insensitive system and a case sensitive system. The symptom of this is that no matter how many times you run the sync it never completes fully.

The local filesystem may or may not be case sensitive depending on OS.

Windows - usually case insensitive, though case is preserved
OSX - usually case insensitive, though it is possible to format case sensitive
Linux - usually case sensitive, but there are case insensitive file systems (eg FAT formatted USB keys)

Most of the time this doesn't cause any problems as people tend to avoid files whose name differs only by case even on case sensitive systems.

Duplicate files

If a cloud storage system allows duplicate files then it can have two objects with the same name.

This confuses rclone greatly when syncing - use the rclone dedupe command to rename or remove duplicates.

Google Drive

Paths are specified as drive:path

Drive paths may be as deep as required, eg drive:directory/subdirectory.

The initial setup for drive involves getting a token from Google drive which you need to do in your browser. rclone config walks you through it.

Here is an example of how to make a remote called remote. First run:

 rclone config

This will guide you through an interactive setup process:

--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y

Note that rclone runs a webserver on your local machine to collect the token as returned from Google if you use auto config mode. This only runs from the moment it opens your browser to the moment you get back the verification code. This is on http://127.0.0.1:53682/ and this it may require you to unblock it temporarily if you are running a host firewall, or use manual mode.

You can then use it like this,

List directories in top level of your drive

rclone lsd remote:

List all the files in your drive

rclone ls remote:

To copy a local directory to a drive directory called backup

rclone copy /home/source remote:backup

Modified time

Google drive stores modification times accurate to 1 ms.

Revisions

Google drive stores revisions of files. When you upload a change to an existing file to google drive using rclone it will create a new revision of that file.

Revisions follow the standard google policy which at time of writing was

They are deleted after 30 days or 100 revisions (whatever comes first).
They do not count towards a user storage quota.

Deleting files

By default rclone will delete files permanently when requested. If sending them to the trash is required instead then use the --drive-use-trash flag.

Specific options

Here are the command line options specific to this cloud storage system.

--drive-chunk-size=SIZE

Upload chunk size. Must a power of 2 >= 256k. Default value is 8 MB.

Making this larger will improve performance, but note that each chunk is buffered in memory one per transfer.

Reducing this will reduce memory usage but decrease performance.

--drive-full-list

No longer does anything - kept for backwards compatibility.

--drive-upload-cutoff=SIZE

File size cutoff for switching to chunked upload. Default is 8 MB.

--drive-use-trash

Send files to the trash instead of deleting permanently. Defaults to off, namely deleting files permanently.

--drive-auth-owner-only

Only consider files owned by the authenticated user. Requires that --drive-full-list=true (default).

--drive-formats

Google documents can only be exported from Google drive. When rclone downloads a Google doc it chooses a format to download depending upon this setting.

By default the formats are docx,xlsx,pptx,svg which are a sensible default for an editable document.

When choosing a format, rclone runs down the list provided in order and chooses the first file format the doc can be exported as from the list. If the file can't be exported to a format on the formats list, then rclone will choose a format from the default list.

If you prefer an archive copy then you might use --drive-formats pdf, or if you prefer openoffice/libreoffice formats you might use --drive-formats ods,odt.

Note that rclone adds the extension to the google doc, so if it is calles My Spreadsheet on google docs, it will be exported as My Spreadsheet.xlsx or My Spreadsheet.pdf etc.

Here are the possible extensions with their corresponding mime types.

Extension	Mime Type	Description
csv	text/csv	Standard CSV format for Spreadsheets
doc	application/msword	Micosoft Office Document
docx	application/vnd.openxmlformats-officedocument.wordprocessingml.document	Microsoft Office Document

xls	application/vnd.ms-excel	Microsoft Office Spreadsheet
xlsx	application/vnd.openxmlformats-officedocument.spreadsheetml.sheet	Microsoft Office Spreadsheet
zip	application/zip	A ZIP file of HTML, Images CSS

Limitations

Drive has quite a lot of rate limiting. This causes rclone to be limited to transferring about 2 files per second only. Individual files may be transferred much faster at 100s of MBytes/s but lots of small files can take a long time.

Making your own client_id

When you use rclone with Google drive in its default configuration you are using rclone's client_id. This is shared between all the rclone users. There is a global rate limit on the number of queries per second that each client_id can do set by Google. rclone already has a high quota and I will continue to make sure it is high enough by contacting Google.

However you might find you get better performance making your own client_id if you are a heavy user. Or you may not depending on exactly how Google have been raising rclone's rate limit.

Here is how to create your own Google Drive client ID for rclone:

Log into the Google API Console with your Google account. It doesn't matter what Google account you use. (It need not be the same account as the Google Drive you want to access)
Select a project or create a new project.
Under Overview, Google APIs, Google Apps APIs, click "Drive API", then "Enable".
Click "Credentials" in the left-side panel (not "Go to credentials", which opens the wizard), then "Create credentials", then "OAuth client ID". It will prompt you to set the OAuth consent screen product name, if you haven't set one already.
Choose an application type of "other", and click "Create". (the default name is fine)
It will show you a client ID and client secret. Use these values in rclone config to add a new remote or edit an existing remote.

(Thanks to @balazer on github for these instructions.)

Amazon S3

Paths are specified as remote:bucket (or remote: for the lsd command.) You may put subdirectories in too, eg remote:bucket/path/to/dir.

Here is an example of making an s3 configuration. First run

This remote is called remote and can now be used like this

See all buckets

rclone lsd remote:

Make a new bucket

rclone mkdir remote:bucket

List the contents of a bucket

rclone ls remote:bucket

Sync /home/local/directory to the remote bucket, deleting any excess files in the bucket.

rclone sync /home/local/directory remote:bucket

Modified time

The modified time is stored as metadata on the object as X-Amz-Meta-Mtime as floating point since the epoch accurate to 1 ns.

Multipart uploads

rclone supports multipart uploads with S3 which means that it can upload files bigger than 5GB. Note that files uploaded with multipart upload don't have an MD5SUM.

Buckets and Regions

With Amazon S3 you can list buckets (rclone lsd) using any region, but you can only access the content of a bucket from the region it was created in. If you attempt to access a bucket from the wrong region, you will get an error, incorrect region, the bucket is not in 'XXX' region.

Authentication

There are two ways to supply rclone with a set of AWS credentials. In order of precedence:

Directly in the rclone configuration file (as configured by rclone config)
- set access_key_id and secret_access_key
Runtime configuration:
- set env_auth to true in the config file
- Exporting the following environment variables before running rclone
  - Access Key ID: AWS_ACCESS_KEY_ID or AWS_ACCESS_KEY
  - Secret Access Key: AWS_SECRET_ACCESS_KEY or AWS_SECRET_KEY
- Running rclone on an EC2 instance with an IAM role

If none of these option actually end up providing rclone with AWS credentials then S3 interaction will be non-authenticated (see below).

Anonymous access to public buckets

If you want to use rclone to access a public bucket, configure with a blank access_key_id and secret_access_key. Eg

No remotes found - make a new one
n) New remote
q) Quit config
n/q> n
name> anons3
What type of source is it?
Choose a number from below
 1) amazon cloud drive
 2) b2
 3) drive
 4) dropbox
 5) google cloud storage
 6) swift
 7) hubic
 8) local
 9) onedrive
10) s3
11) yandex
type> 10
Get AWS credentials from runtime (environment variables or EC2 meta data if no env vars). Only applies if access_key_id and secret_access_key is blank.
Choose a number from below, or type in your own value
 * Enter AWS credentials in the next step
 1) false
 * Get AWS credentials from the environment (env vars or IAM)
 2) true
env_auth> 1
AWS Access Key ID - leave blank for anonymous access or runtime credentials.
access_key_id>
AWS Secret Access Key (password) - leave blank for anonymous access or runtime credentials.
secret_access_key>
...

Then use it as normal with the name of the public bucket, eg

rclone lsd anons3:1000genomes

You will be able to list and copy data but not upload it.

Ceph

Ceph is an object storage system which presents an Amazon S3 interface.

To use rclone with ceph, you need to set the following parameters in the config.

access_key_id = Whatever
secret_access_key = Whatever
endpoint = https://ceph.endpoint.goes.here/
region = other-v2-signature

Note also that Ceph sometimes puts / in the passwords it gives users. If you read the secret access key using the command line tools you will get a JSON blob with the / escaped as \/. Make sure you only write / in the secret access key.

Eg the dump from Ceph looks something like this (irrelevant keys removed).

{
    "user_id": "xxx",
    "display_name": "xxxx",
    "keys": [
        {
            "user": "xxx",
            "access_key": "xxxxxx",
            "secret_key": "xxxxxx\/xxxx"
        }
    ],
}

Because this is a json dump, it is encoding the / as \/, so if you use the secret key as xxxxxx/xxxx it will work fine.

Minio

Minio is an object storage server built for cloud application developers and devops.

It is very easy to install and provides an S3 compatible server which can be used by rclone.

To use it, install Minio following the instructions from the web site.

When it configures itself Minio will print something like this

AccessKey: WLGDGYAQYIGI833EV05A  SecretKey: BYvgJM101sHngl2uzjXS/OBF/aMxAN06JrJ3qJlF Region: us-east-1

Minio Object Storage:
     http://127.0.0.1:9000
     http://10.0.0.3:9000

Minio Browser:
     http://127.0.0.1:9000
     http://10.0.0.3:9000

These details need to go into rclone config like this. Note that it is important to put the region in as stated above.

env_auth> 1
access_key_id> WLGDGYAQYIGI833EV05A
secret_access_key> BYvgJM101sHngl2uzjXS/OBF/aMxAN06JrJ3qJlF   
region> us-east-1
endpoint> http://10.0.0.3:9000
location_constraint> 
server_side_encryption>

Which makes the config file look like this

[minio]
env_auth = false
access_key_id = WLGDGYAQYIGI833EV05A
secret_access_key = BYvgJM101sHngl2uzjXS/OBF/aMxAN06JrJ3qJlF
region = us-east-1
endpoint = http://10.0.0.3:9000
location_constraint = 
server_side_encryption =

Minio doesn't support all the features of S3 yet. In particular it doesn't support MD5 checksums (ETags) or metadata. This means rclone can't check MD5SUMs or store the modified date. However you can work around this with the --size-only flag of rclone.

So once set up, for example to copy files into a bucket

rclone --size-only copy /path/to/files minio:bucket

Swift

Swift refers to Openstack Object Storage. Commercial implementations of that being:

Paths are specified as remote:container (or remote: for the lsd command.) You may put subdirectories in too, eg remote:container/path/to/dir.

Here is an example of making a swift configuration. First run

This remote is called remote and can now be used like this

See all containers

rclone lsd remote:

Make a new container

rclone mkdir remote:container

List the contents of a container

rclone ls remote:container

Sync /home/local/directory to the remote container, deleting any excess files in the container.

rclone sync /home/local/directory remote:container

Specific options

Here are the command line options specific to this cloud storage system.

--swift-chunk-size=SIZE

Above this size files will be chunked into a _segments container. The default for this is 5GB which is its maximum value.

Modified time

The modified time is stored as metadata on the object as X-Object-Meta-Mtime as floating point since the epoch accurate to 1 ns.

This is a defacto standard (used in the official python-swiftclient amongst others) for storing the modification time for an object.

Limitations

The Swift API doesn't return a correct MD5SUM for segmented files (Dynamic or Static Large Objects) so rclone won't check or use the MD5SUM for these.

Troubleshooting

Rclone gives Failed to create file system for "remote:": Bad Request

Due to an oddity of the underlying swift library, it gives a "Bad Request" error rather than a more sensible error when the authentication fails for Swift.

So this most likely means your username / password is wrong. You can investigate further with the --dump-bodies flag.

Rclone gives Failed to create file system: Response didn't have storage storage url and auth token

This is most likely caused by forgetting to specify your tenant when setting up a swift remote.

Dropbox

Paths are specified as remote:path

Dropbox paths may be as deep as required, eg remote:directory/subdirectory.

The initial setup for dropbox involves getting a token from Dropbox which you need to do in your browser. rclone config walks you through it.

Here is an example of how to make a remote called remote. First run:

You can then use it like this,

List directories in top level of your dropbox

rclone lsd remote:

List all the files in your dropbox

rclone ls remote:

To copy a local directory to a dropbox directory called backup

rclone copy /home/source remote:backup

Modified time and MD5SUMs

Dropbox doesn't provide the ability to set modification times in the V1 public API, so rclone can't support modified time with Dropbox.

This may change in the future - see these issues for details:

Dropbox doesn't return any sort of checksum (MD5 or SHA1).

Together that means that syncs to dropbox will effectively have the --size-only flag set.

Specific options

Here are the command line options specific to this cloud storage system.

--dropbox-chunk-size=SIZE

Upload chunk size. Max 150M. The default is 128MB. Note that this isn't buffered into memory.

Limitations

Note that Dropbox is case insensitive so you can't have a file called "Hello.doc" and one called "hello.doc".

There are some file names such as thumbs.db which Dropbox can't store. There is a full list of them in the "Ignored Files" section of this document. Rclone will issue an error message File name disallowed - not uploading if it attempt to upload one of those file names, but the sync won't fail.

If you have more than 10,000 files in a directory then rclone purge dropbox:dir will return the error Failed to purge: There are too many files involved in this operation. As a work-around do an rclone delete dropbix:dir followed by an rclone rmdir dropbox:dir.

Google Cloud Storage

Paths are specified as remote:bucket (or remote: for the lsd command.) You may put subdirectories in too, eg remote:bucket/path/to/dir.

rclone mkdir remote:bucket

List the contents of a bucket

rclone ls remote:bucket

Sync /home/local/directory to the remote bucket, deleting any excess files in the bucket.

rclone sync /home/local/directory remote:bucket

Service Account support

You can set up rclone with Google Cloud Storage in an unattended mode, i.e. not tied to a specific end-user Google account. This is useful when you want to synchronise files onto machines that don't have actively logged-in users, for example build machines.

To get credentials for Google Cloud Platform IAM Service Accounts, please head to the Service Account section of the Google Developer Console. Service Accounts behave just like normal User permissions in Google Cloud Storage ACLs, so you can limit their access (e.g. make them read only). After creating an account, a JSON file containing the Service Account's credentials will be downloaded onto your machines. These credentials are what rclone will use for authentication.

To use a Service Account instead of OAuth2 token flow, enter the path to your Service Account credentials at the service_account_file prompt and rclone won't use the browser based authentication flow.

Modified time

Google google cloud storage stores md5sums natively and rclone stores modification times as metadata on the object, under the "mtime" key in RFC3339 format accurate to 1ns.

Amazon Drive

Paths are specified as remote:path

Paths may be as deep as required, eg remote:directory/subdirectory.

The initial setup for Amazon Drive involves getting a token from Amazon which you need to do in your browser. rclone config walks you through it.

See the remote setup docs for how to set it up on a machine with no Internet browser available.

Note that rclone runs a webserver on your local machine to collect the token as returned from Amazon. This only runs from the moment it opens your browser to the moment you get back the verification code. This is on http://127.0.0.1:53682/ and this it may require you to unblock it temporarily if you are running a host firewall.

Once configured you can then use rclone like this,

List directories in top level of your Amazon Drive

rclone lsd remote:

List all the files in your Amazon Drive

rclone ls remote:

To copy a local directory to an Amazon Drive directory called backup

rclone copy /home/source remote:backup

Modified time and MD5SUMs

Amazon Drive doesn't allow modification times to be changed via the API so these won't be accurate or used for syncing.

It does store MD5SUMs so for a more accurate sync, you can use the --checksum flag.

Deleting files

Any files you delete with rclone will end up in the trash. Amazon don't provide an API to permanently delete files, nor to empty the trash, so you will have to do that with one of Amazon's apps or via the Amazon Drive website.

Specific options

Here are the command line options specific to this cloud storage system.

--acd-templink-threshold=SIZE

Files this size or more will be downloaded via their tempLink. This is to work around a problem with Amazon Drive which blocks downloads of files bigger than about 10GB. The default for this is 9GB which shouldn't need to be changed.

To download files above this threshold, rclone requests a tempLink which downloads the file through a temporary URL directly from the underlying S3 storage.

--acd-upload-wait-time=TIME

Sometimes Amazon Drive gives an error when a file has been fully uploaded but the file appears anyway after a little while. This controls the time rclone waits - 2 minutes by default. You might want to increase the time if you are having problems with very big files. Upload with the -v flag for more info.

Limitations

Note that Amazon Drive is case insensitive so you can't have a file called "Hello.doc" and one called "hello.doc".

Amazon Drive has rate limiting so you may notice errors in the sync (429 errors). rclone will automatically retry the sync up to 3 times by default (see --retries flag) which should hopefully work around this problem.

Amazon Drive has an internal limit of file sizes that can be uploaded to the service. This limit is not officially published, but all files larger than this will fail.

At the time of writing (Jan 2016) is in the area of 50GB per file. This means that larger files are likely to fail.

Unfortunatly there is no way for rclone to see that this failure is because of file size, so it will retry the operation, as any other failure. To avoid this problem, use --max-size=50GB option to limit the maximum size of uploaded files.

Microsoft One Drive

Paths are specified as remote:path

Paths may be as deep as required, eg remote:directory/subdirectory.

The initial setup for One Drive involves getting a token from Microsoft which you need to do in your browser. rclone config walks you through it.

To copy a local directory to an One Drive directory called backup

rclone copy /home/source remote:backup

Modified time and hashes

One Drive allows modification times to be set on objects accurate to 1 second. These will be used to detect whether objects need syncing or not.

One drive supports SHA1 type hashes, so you can use --checksum flag.

Deleting files

Any files you delete with rclone will end up in the trash. Microsoft doesn't provide an API to permanently delete files, nor to empty the trash, so you will have to do that with one of Microsoft's apps or via the One Drive website.

Specific options

Here are the command line options specific to this cloud storage system.

--onedrive-chunk-size=SIZE

Above this size files will be chunked - must be multiple of 320k. The default is 10MB. Note that the chunks will be buffered into memory.

--onedrive-upload-cutoff=SIZE

Cutoff for switching to chunked upload - must be <= 100MB. The default is 10MB.

Limitations

Note that One Drive is case insensitive so you can't have a file called "Hello.doc" and one called "hello.doc".

Rclone only supports your default One Drive, and doesn't work with One Drive for business. Both these issues may be fixed at some point depending on user demand!

There are quite a few characters that can't be in One Drive file names. These can't occur on Windows platforms, but on non-Windows platforms they are common. Rclone will map these names to and from an identical looking unicode equivalent. For example if a file has a ? in it will be mapped to ？ instead.

Hubic

Paths are specified as remote:path

Paths are specified as remote:container (or remote: for the lsd command.) You may put subdirectories in too, eg remote:container/path/to/dir.

The initial setup for Hubic involves getting a token from Hubic which you need to do in your browser. rclone config walks you through it.

Here is an example of how to make a remote called remote. First run:

 rclone config

This will guide you through an interactive setup process:

y/e/d> y

See the remote setup docs for how to set it up on a machine with no Internet browser available.

Note that rclone runs a webserver on your local machine to collect the token as returned from Hubic. This only runs from the moment it opens your browser to the moment you get back the verification code. This is on http://127.0.0.1:53682/ and this it may require you to unblock it temporarily if you are running a host firewall.

Once configured you can then use rclone like this,

List containers in the top level of your Hubic

rclone lsd remote:

List all the files in your Hubic

rclone ls remote:

To copy a local directory to an Hubic directory called backup

rclone copy /home/source remote:backup

If you want the directory to be visible in the official Hubic browser, you need to copy your files to the default directory

rclone copy /home/source remote:default/backup

Modified time

The modified time is stored as metadata on the object as X-Object-Meta-Mtime as floating point since the epoch accurate to 1 ns.

This is a defacto standard (used in the official python-swiftclient amongst others) for storing the modification time for an object.

Note that Hubic wraps the Swift backend, so most of the properties of are the same.

Limitations

This uses the normal OpenStack Swift mechanism to refresh the Swift API credentials and ignores the expires field returned by the Hubic API.

The Swift API doesn't return a correct MD5SUM for segmented files (Dynamic or Static Large Objects) so rclone won't check or use the MD5SUM for these.

Backblaze B2

B2 is Backblaze's cloud storage system.

Paths are specified as remote:bucket (or remote: for the lsd command.) You may put subdirectories in too, eg remote:bucket/path/to/dir.

Here is an example of making a b2 configuration. First run

rclone config

This will guide you through an interactive setup process. You will need your account number (a short hex number) and key (a long hex number) which you can get from the b2 control panel.

This remote is called remote and can now be used like this

See all buckets

rclone lsd remote:

Make a new bucket

rclone mkdir remote:bucket

List the contents of a bucket

rclone ls remote:bucket

Sync /home/local/directory to the remote bucket, deleting any excess files in the bucket.

rclone sync /home/local/directory remote:bucket

Modified time

The modified time is stored as metadata on the object as X-Bz-Info-src_last_modified_millis as milliseconds since 1970-01-01 in the Backblaze standard. Other tools should be able to use this as a modified time.

Modified times are used in syncing and are fully supported except in the case of updating a modification time on an existing object. In this case the object will be uploaded again as B2 doesn't have an API method to set the modification time independent of doing an upload.

SHA1 checksums

The SHA1 checksums of the files are checked on upload and download and will be used in the syncing process.

Large files which are uploaded in chunks will store their SHA1 on the object as X-Bz-Info-large_file_sha1 as recommended by Backblaze.

Transfers

Backblaze recommends that you do lots of transfers simultaneously for maximum speed. In tests from my SSD equiped laptop the optimum setting is about --transfers 32 though higher numbers may be used for a slight speed improvement. The optimum number for you may vary depending on your hardware, how big the files are, how much you want to load your computer, etc. The default of --transfers 4 is definitely too low for Backblaze B2 though.

Note that uploading big files (bigger than 200 MB by default) will use a 96 MB RAM buffer by default. There can be at most --transfers of these in use at any moment, so this sets the upper limit on the memory used.

Versions

When rclone uploads a new version of a file it creates a new version of it. Likewise when you delete a file, the old version will still be available.

Old versions of files are visible using the --b2-versions flag.

If you wish to remove all the old versions then you can use the rclone cleanup remote:bucket command which will delete all the old versions of files, leaving the current ones intact. You can also supply a path and only old versions under that path will be deleted, eg rclone cleanup remote:bucket/path/to/stuff.

When you purge a bucket, the current and the old versions will be deleted then the bucket will be deleted.

However delete will cause the current versions of the files to become hidden old versions.

Here is a session showing the listing and and retreival of an old version followed by a cleanup of the old versions.

Show current version and all the versions with --b2-versions flag.

$ rclone -q ls b2:cleanup-test
        9 one.txt

$ rclone -q --b2-versions ls b2:cleanup-test
        9 one.txt
        8 one-v2016-07-04-141032-000.txt
       16 one-v2016-07-04-141003-000.txt
       15 one-v2016-07-02-155621-000.txt

Retreive an old verson

$ rclone -q --b2-versions copy b2:cleanup-test/one-v2016-07-04-141003-000.txt /tmp

$ ls -l /tmp/one-v2016-07-04-141003-000.txt
-rw-rw-r-- 1 ncw ncw 16 Jul  2 17:46 /tmp/one-v2016-07-04-141003-000.txt

Clean up all the old versions and show that they've gone.

$ rclone -q cleanup b2:cleanup-test

$ rclone -q ls b2:cleanup-test
        9 one.txt

$ rclone -q --b2-versions ls b2:cleanup-test
        9 one.txt

Specific options

Here are the command line options specific to this cloud storage system.

--b2-chunk-size valuee=SIZE

When uploading large files chunk the file into this size. Note that these chunks are buffered in memory and there might a maximum of --transfers chunks in progress at once. 100,000,000 Bytes is the minimim size (default 96M).

--b2-upload-cutoff=SIZE

Cutoff for switching to chunked upload (default 190.735 MiB == 200 MB). Files above this size will be uploaded in chunks of --b2-chunk-size.

This value should be set no larger than 4.657GiB (== 5GB) as this is the largest file size that can be uploaded.

--b2-test-mode=FLAG

This is for debugging purposes only.

Setting FLAG to one of the strings below will cause b2 to return specific errors for debugging purposes.

fail_some_uploads
expire_some_account_authorization_tokens
force_cap_exceeded

These will be set in the X-Bz-Test-Mode header which is documented in the b2 integrations checklist.

--b2-versions

When set rclone will show and act on older versions of files. For example

Listing without --b2-versions

$ rclone -q ls b2:cleanup-test
        9 one.txt

And with

$ rclone -q --b2-versions ls b2:cleanup-test
        9 one.txt
        8 one-v2016-07-04-141032-000.txt
       16 one-v2016-07-04-141003-000.txt
       15 one-v2016-07-02-155621-000.txt

Showing that the current version is unchanged but older versions can be seen. These have the UTC date that they were uploaded to the server to the nearest millisecond appended to them.

Note that when using --b2-versions no file write operations are permitted, so you can't upload files or delete them.

Yandex Disk

Yandex Disk is a cloud storage solution created by Yandex.

Yandex paths may be as deep as required, eg remote:directory/subdirectory.

Here is an example of making a yandex configuration. First run

See the remote setup docs for how to set it up on a machine with no Internet browser available.

Note that rclone runs a webserver on your local machine to collect the token as returned from Yandex Disk. This only runs from the moment it opens your browser to the moment you get back the verification code. This is on http://127.0.0.1:53682/ and this it may require you to unblock it temporarily if you are running a host firewall.

Once configured you can then use rclone like this,

See top level directories

rclone lsd remote:

Make a new directory

rclone mkdir remote:directory

List the contents of a directory

rclone ls remote:directory

Sync /home/local/directory to the remote path, deleting any excess files in the path.

rclone sync /home/local/directory remote:directory

Modified time

Modified times are supported and are stored accurate to 1 ns in custom metadata called rclone_modified in RFC3339 with nanoseconds format.

MD5 checksums

MD5 checksums are natively supported by Yandex Disk.

Crypt

The crypt remote encrypts and decrypts another remote.

To use it first set up the underlying remote following the config instructions for that remote. You can also use a local pathname instead of a remote which will encrypt and decrypt from that directory which might be useful for encrypting onto a USB stick for example.

First check your chosen remote is working - we'll call it remote:path in these docs. Note that anything inside remote:path will be encrypted and anything outside won't. This means that if you are using a bucket based remote (eg S3, B2, swift) then you should probably put the bucket in the remote s3:bucket. If you just use s3: then rclone will make encrypted bucket names too (if using file name encryption) which may or may not be what you want.

Now configure crypt using rclone config. We will call this one secret to differentiate it from the remote.

Important The password is stored in the config file is lightly obscured so it isn't immediately obvious what it is. It is in no way secure unless you use config file encryption.

A long passphrase is recommended, or you can use a random one. Note that if you reconfigure rclone with the same passwords/passphrases elsewhere it will be compatible - all the secrets used are derived from those two passwords/passphrases.

Note that rclone does not encrypt

file length - this can be calcuated within 16 bytes
modification time - used for syncing

Example

To test I made a little directory of files using "standard" file name encryption.

plaintext/
├── file0.txt
├── file1.txt
└── subdir
    ├── file2.txt
    ├── file3.txt
    └── subsubdir
        └── file4.txt

Copy these to the remote and list them back

$ rclone -q copy plaintext secret:
$ rclone -q ls secret:
        7 file1.txt
        6 file0.txt
        8 subdir/file2.txt
       10 subdir/subsubdir/file4.txt
        9 subdir/file3.txt

Now see what that looked like when encrypted

$ rclone -q ls remote:path
       55 hagjclgavj2mbiqm6u6cnjjqcg
       54 v05749mltvv1tf4onltun46gls
       57 86vhrsv86mpbtd3a0akjuqslj8/dlj7fkq4kdq72emafg7a7s41uo

       56 86vhrsv86mpbtd3a0akjuqslj8/8njh1sk437gttmep3p70g81aps

Note that this retains the directory structure which means you can do this

$ rclone -q ls secret:subdir
        8 file2.txt
        9 file3.txt
       10 subsubdir/file4.txt

If don't use file name encryption then the remote will look like this

note the .bin extensions added to prevent the cloud provider attempting to interpret the data.

$ rclone -q ls remote:path
       54 file0.txt.bin
       57 subdir/file3.txt.bin
       56 subdir/file2.txt.bin
       58 subdir/subsubdir/file4.txt.bin
       55 file1.txt.bin

File name encryption modes

Here are some of the features of the file name encryption modes

Off

doesn't hide file names or directory structure
allows for longer file names (~246 characters)
can use sub paths and copy single files

Standard

file names encrypted
file names can't be as long (~156 characters)
can use sub paths and copy single files
directory structure visibile
identical files names will have identical uploaded names
can use shortcuts to shorten the directory recursion

Cloud storage systems have various limits on file name length and total path length which you are more likely to hit using "Standard" file name encryption. If you keep your file names to below 156 characters in length then you should be OK on all providers.

There may be an even more secure file name encryption mode in the future which will address the long file name problem.

File formats

File encryption

Files are encrypted 1:1 source file to destination object. The file has a header and is divided into chunks.

Header

8 bytes magic string RCLONE\x00\x00
24 bytes Nonce (IV)

The initial nonce is generated from the operating systems crypto strong random number genrator. The nonce is incremented for each chunk read making sure each nonce is unique for each block written. The chance of a nonce being re-used is miniscule. If you wrote an exabyte of data (10¹⁸ bytes) you would have a probability of approximately 2×10⁻³² of re-using a nonce.

Chunk

Each chunk will contain 64kB of data, except for the last one which may have less data. The data chunk is in standard NACL secretbox format. Secretbox uses XSalsa20 and Poly1305 to encrypt and authenticate messages.

Each chunk contains:

16 Bytes of Poly1305 authenticator
1 - 65536 bytes XSalsa20 encrypted data

64k chunk size was chosen as the best performing chunk size (the authenticator takes too much time below this and the performance drops off due to cache effects above this). Note that these chunks are buffered in memory so they can't be too big.

This uses a 32 byte (256 bit key) key derived from the user password.

Examples

1 byte file will encrypt to

32 bytes header
17 bytes data chunk

49 bytes total

1MB (1048576 bytes) file will encrypt to

32 bytes header
16 chunks of 65568 bytes

1049120 bytes total (a 0.05% overhead). This is the overhead for big files.

Name encryption

File names are encrypted segment by segment - the path is broken up into / separated strings and these are encrypted individually.

File segments are padded using using PKCS#7 to a multiple of 16 bytes before encryption.

They are then encrypted with EME using AES with 256 bit key. EME (ECB-Mix-ECB) is a wide-block encryption mode presented in the 2003 paper "A Parallelizable Enciphering Mode" by Halevi and Rogaway.

This makes for determinstic encryption which is what we want - the same filename must encrypt to the same thing otherwise we can't find it on the cloud storage system.

This means that

filenames with the same name will encrypt the same
filenames which start the same won't have a common prefix

This uses a 32 byte key (256 bits) and a 16 byte (128 bits) IV both of which are derived from the user password.

After encryption they are written out using a modified version of standard base32 encoding as described in RFC4648. The standard encoding is modified in two ways:

it becomes lower case (no-one likes upper case filenames!)
we strip the padding character =

base32 is used rather than the more efficient base64 so rclone can be used on case insensitive remotes (eg Windows, Amazon Drive).

Key derivation

Rclone uses scrypt with parameters N=16384, r=8, p=1 with a an optional user supplied salt (password2) to derive the 32+32+16 = 80 bytes of key material required. If the user doesn't supply a salt then rclone uses an internal one.

scrypt makes it impractical to mount a dictionary attack on rclone encrypted data. For full protection agains this you should always use a salt.

Local Filesystem

Local paths are specified as normal filesystem paths, eg /path/to/wherever, so

rclone sync /home/source /tmp/destination

Will sync /home/source to /tmp/destination

These can be configured into the config file for consistencies sake, but it is probably easier not to.

Modified time

Rclone reads and writes the modified time using an accuracy determined by the OS. Typically this is 1ns on Linux, 10 ns on Windows and 1 Second on OS X.

Filenames

Filenames are expected to be encoded in UTF-8 on disk. This is the normal case for Windows and OS X.

There is a bit more uncertainty in the Linux world, but new distributions will have UTF-8 encoded files names. If you are using an old Linux filesystem with non UTF-8 file names (eg latin1) then you can use the convmv tool to convert the filesystem to UTF-8. This tool is available in most distributions' package managers.

If an invalid (non-UTF8) filename is read, the invalid caracters will be replaced with the unicode replacement character, '�'. rclone will emit a debug message in this case (use -v to see), eg

Local file system at .: Replacing invalid UTF-8 characters in "gro\xdf"

Long paths on Windows

Rclone handles long paths automatically, by converting all paths to long UNC paths which allows paths up to 32,767 characters.

This is why you will see that your paths, for instance c:\files is converted to the UNC path \\?\c:\files in the output, and \\server\share is converted to \\?\UNC\server\share.

However, in rare cases this may cause problems with buggy file system drivers like EncFS. To disable UNC conversion globally, add this to your .rclone.conf file:

[local]
nounc = true

If you want to selectively disable UNC, you can add it to a separate entry like this:

[nounc]
type = local
nounc = true

And use rclone like this:

rclone copy c:\src nounc:z:\dst

This will use UNC paths on c:\src but not on z:\dst. Of course this will cause problems if the absolute path length of a file exceeds 258 characters on z, so only use this option if you have to.

Bugs and Limitations

Empty directories are left behind / not created

With remotes that have a concept of directory, eg Local and Drive, empty directories may be left behind, or not created when one was expected.

This is because rclone doesn't have a concept of a directory - it only works on objects. Most of the object storage systems can't actually store a directory so there is nowhere for rclone to store anything about directories.

You can work round this to some extent with thepurge command which will delete everything under the path, inluding empty directories.

This may be fixed at some point in Issue #100

Directory timestamps aren't preserved

For the same reason as the above, rclone doesn't have a concept of a directory - it only works on objects, therefore it can't preserve the timestamps of directories.

Frequently Asked Questions

Do all cloud storage systems support all rclone commands

Yes they do. All the rclone commands (eg sync, copy etc) will work on all the remote storage systems.

Can I copy the config from one machine to another

Sure! Rclone stores all of its config in a single file. If you want to find this file, the simplest way is to run rclone -h and look at the help for the --config flag which will tell you where it is.

See the remote setup docs for more info.

How do I configure rclone on a remote / headless box with no browser?

This has now been documented in its own remote setup page.

Can rclone sync directly from drive to s3

Rclone can sync between two remote cloud storage systems just fine.

Note that it effectively downloads the file and uploads it again, so the node running rclone would need to have lots of bandwidth.

The syncs would be incremental (on a file by file basis).

rclone sync drive:Folder s3:bucket

Using rclone from multiple locations at the same time

You can use rclone from multiple places at the same time if you choose different subdirectory for the output, eg

Server A> rclone sync /tmp/whatever remote:ServerA
Server B> rclone sync /tmp/whatever remote:ServerB

If you sync to the same directory then you should use rclone copy otherwise the two rclones may delete each others files, eg

Server A> rclone copy /tmp/whatever remote:Backup
Server B> rclone copy /tmp/whatever remote:Backup

The file names you upload from Server A and Server B should be different in this case, otherwise some file systems (eg Drive) may make duplicates.

Why doesn't rclone support partial transfers / binary diffs like rsync?

Rclone stores each file you transfer as a native object on the remote cloud storage system. This means that you can see the files you upload as expected using alternative access methods (eg using the Google Drive web interface). There is a 1:1 mapping between files on your hard disk and objects created in the cloud storage system.

Cloud storage systems (at least none I've come across yet) don't support partially uploading an object. You can't take an existing object, and change some bytes in the middle of it.

It would be possible to make a sync system which stored binary diffs instead of whole objects like rclone does, but that would break the 1:1 mapping of files on your hard disk to objects in the remote cloud storage system.

All the cloud storage systems support partial downloads of content, so it would be possible to make partial downloads work. However to make this work efficiently this would require storing a significant amount of metadata, which breaks the desired 1:1 mapping of files to objects.

Can rclone do bi-directional sync?

No, not at present. rclone only does uni-directional sync from A -> B. It may do in the future though since it has all the primitives - it just requires writing the algorithm to do it.

Can I use rclone with an HTTP proxy?

Yes. rclone will use the environment variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY, similar to cURL and other programs.

HTTPS_PROXY takes precedence over HTTP_PROXY for https requests.

The environment values may be either a complete URL or a "host[:port]", in which case the "http" scheme is assumed.

The NO_PROXY allows you to disable the proxy for specific hosts. Hosts must be comma separated, and can contain domains or parts. For instance "foo.com" also matches "bar.foo.com".

Rclone gives x509: failed to load system roots and no roots provided error

This means that rclone can't file the SSL root certificates. Likely you are running rclone on a NAS with a cut-down Linux OS, or possibly on Solaris.

Rclone (via the Go runtime) tries to load the root certificates from these places on Linux.

"/etc/ssl/certs/ca-certificates.crt", // Debian/Ubuntu/Gentoo etc.
"/etc/pki/tls/certs/ca-bundle.crt",   // Fedora/RHEL
"/etc/ssl/ca-bundle.pem",             // OpenSUSE
"/etc/pki/tls/cacert.pem",            // OpenELEC

So doing something like this should fix the problem. It also sets the time which is important for SSL to work properly.

mkdir -p /etc/ssl/certs/
curl -o /etc/ssl/certs/ca-certificates.crt https://raw.githubusercontent.com/bagder/ca-bundle/master/ca-bundle.crt
ntpclient -s -h pool.ntp.org

Note that you may need to add the --insecure option to the curl command line if it doesn't work without.

curl --insecure -o /etc/ssl/certs/ca-certificates.crt https://raw.githubusercontent.com/bagder/ca-bundle/master/ca-bundle.crt

Rclone gives Failed to load config file: function not implemented error

Likely this means that you are running rclone on Linux version not supported by the go runtime, ie earlier than version 2.6.23.

See the system requirements section in the go install docs for full details.

All my uploaded docx/xlsx/pptx files appear as archive/zip

This is caused by uploading these files from a Windows computer which hasn't got the Microsoft Office suite installed. The easiest way to fix is to install the Word viewer and the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 and later versions' file formats
