Install
-------

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

[Download](/downloads/) the relevant binary.

Or alternatively if you have Go installed use

    go get github.com/ncw/rclone

and this will build the binary in `$GOPATH/bin`.

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 below for detailed instructions for

  * [Google drive](/drive/)
  * [Amazon S3](/s3/)
  * [Swift / Rackspace Cloudfiles / Memset Memstore](/swift/)
  * [Local filesystem](/local/)

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 copy source:path dest:path

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

    rclone sync source:path dest:path

Sync the source to the destination.  Doesn't transfer
unchanged files, testing first by modification time then by
size.  Deletes any files that exist in source that don't
exist in destination. Since this can cause data loss, test
first with the `--dry-run` flag.

    rclone ls [remote:path]

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

    rclone lsd [remote:path]

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

    rclone lsl [remote:path]

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

    rclone md5sum [remote:path]

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

    rclone mkdir remote:path

Make the path if it doesn't already exist

    rclone rmdir remote:path

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

    rclone purge remote:path

Remove the path and all of its contents.

    rclone check source:path dest:path

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.

    rclone config 

Enter an interactive configuration session.
