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:

No remotes found - make a new one
n) New remote
r) Rename remote
c) Copy remote
s) Set configuration password
q) Quit config
n/r/c/s/q> n

   | File authorization is revoked when the user deauthorizes the app.
   \ "drive.file"
   / Allows read and write access to the Application Data folder.
 4 | This is not visible in the drive website.
   \ "drive.appfolder"

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

Scopes

Rclone allows you to select which scope you would like for rclone to use. This changes what type of token is granted to rclone. The scopes are defined here..

The scope are

drive

This is the default scope and allows full access to all files, except for the Application Data Folder (see below).

Choose this one if you aren't sure.

drive.readonly

This allows read only access to all files. Files may be listed and downloaded but not uploaded, renamed or deleted.

drive.file

With this scope rclone can read/view/modify only those files and folders it creates.

So if you uploaded files to drive via the web interface (or any other means) they will not be visible to rclone.

This can be useful if you are using rclone to backup data and you want to be sure confidential data on your drive is not visible to rclone.

Files created with this scope are visible in the web interface.

drive.appfolder

This gives rclone its own private area to store files. Rclone will not be able to see any other files on your drive and you won't be able to see rclone's files from the web interface either.

drive.metadata.readonly

This allows read only access to file names only. It does not allow rclone to download or upload data, or rename or delete files or directories.

Root folder ID

You can set the root_folder_id for rclone. This is the directory (identified by its Folder ID) that rclone considers to be a the root of your drive.

Normally you will leave this blank and rclone will determine the correct root to use itself.

However you can set this to restrict rclone to a specific folder hierarchy or to access data within the "Computers" tab on the drive web interface (where files from Google's Backup and Sync desktop program go).

In order to do this you will have to find the Folder ID of the directory you wish rclone to display. This will be the last segment of the URL when you open the relevant folder in the drive web interface.

So if the folder you want rclone to use has a URL which looks like https://drive.google.com/drive/folders/1XyfxxxxxxxxxxxxxxxxxxxxxxxxxKHCh in the browser, then you use 1XyfxxxxxxxxxxxxxxxxxxxxxxxxxKHCh as the root_folder_id in the config.

NB folders under the "Computers" tab seem to be read only (drive gives a 500 error) when using rclone.

There doesn't appear to be an API to discover the folder IDs of the "Computers" tab - please contact us if you know otherwise!

Note also that rclone can't access any data under the "Backups" tab on the google drive web interface yet.

Service Account support

You can set up rclone with Google Drive 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 use a Service Account instead of OAuth2 token flow, enter the path to your Service Account credentials at the service_account_file prompt during rclone config and rclone won't use the browser based authentication flow. If you'd rather stuff the contents of the credentials file into the rclone config file, you can set service_account_credentials with the actual contents of the file instead, or set the equivalent environment variable.

Use case - Google Apps/G-suite account and individual Drive

Let's say that you are the administrator of a Google Apps (old) or G-suite account. The goal is to store data on an individual's Drive account, who IS a member of the domain. We'll call the domain example.com, and the user foo@example.com.

There's a few steps we need to go through to accomplish this:

1. Create a service account for example.com

To create a service account and obtain its credentials, go to the Google Developer Console.
You must have a project - create one if you don't.
Then go to "IAM & admin" -> "Service Accounts".
Use the "Create Credentials" button. Fill in "Service account name" with something that identifies your client. "Role" can be empty.
Tick "Furnish a new private key" - select "Key type JSON".
Tick "Enable G Suite Domain-wide Delegation". This option makes "impersonation" possible, as documented here: Delegating domain-wide authority to the service account
These credentials are what rclone will use for authentication. If you ever need to remove access, press the "Delete service account key" button.

2. Allowing API access to example.com Google Drive

Go to example.com's admin console
Go into "Security" (or use the search bar)
Select "Show more" and then "Advanced settings"
Select "Manage API client access" in the "Authentication" section
In the "Client Name" field enter the service account's "Client ID" - this can be found in the Developer Console under "IAM & Admin" -> "Service Accounts", then "View Client ID" for the newly created service account. It is a ~21 character numerical string.
In the next field, "One or More API Scopes", enter https://www.googleapis.com/auth/drive to grant access to Google Drive specifically.

3. Configure rclone, assuming a new install

rclone config

n/s/q> n         # New
name>gdrive      # Gdrive is an example name
Storage>         # Select the number shown for Google Drive
client_id>       # Can be left blank
client_secret>   # Can be left blank
scope>           # Select your scope, 1 for example
root_folder_id>  # Can be left blank
service_account_file> /home/foo/myJSONfile.json # This is where the JSON file goes!
y/n>             # Auto config, y

4. Verify that it's working

rclone -v --drive-impersonate foo@example.com lsf gdrive:backup
The arguments do:
- -v - verbose logging
- --drive-impersonate foo@example.com - this is what does the magic, pretending to be user foo.
- lsf - list files in a parsing friendly way
- gdrive:backup - use the remote called gdrive, work in the folder named backup.

Team drives

If you want to configure the remote to point to a Google Team Drive then answer y to the question Configure this as a team drive?.

This will fetch the list of Team Drives from google and allow you to configure which one you want to use. You can also type in a team drive ID if you prefer.

For example:

Configure this as a team drive?
y) Yes
n) No
y/n> y
Fetching team drive list...
Choose a number from below, or type in your own value
 1 / Rclone Test
   \ "xxxxxxxxxxxxxxxxxxxx"
 2 / Rclone Test 2
   \ "yyyyyyyyyyyyyyyyyyyy"
 3 / Rclone Test 3
   \ "zzzzzzzzzzzzzzzzzzzz"
Enter a Team Drive ID> 1
--------------------
[remote]
client_id =
client_secret =
token = {"AccessToken":"xxxx.x.xxxxx_xxxxxxxxxxx_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx","RefreshToken":"1/xxxxxxxxxxxxxxxx_xxxxxxxxxxxxxxxxxxxxxxxxxx","Expiry":"2014-03-16T13:57:58.955387075Z","Extra":null}
team_drive = xxxxxxxxxxxxxxxxxxxx
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y

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 send all files to the trash when deleting files. If deleting them permanently is required then use the --drive-use-trash=false flag, or set the equivalent environment variable.

Emptying trash

If you wish to empty your trash you can use the rclone cleanup remote: command which will permanently delete all your trashed files. This command does not take any path arguments.

Quota information

To view your current quota you can use the rclone about remote: command which will display your usage limit (quota), the usage in Google Drive, the size of all files in the Trash and the space used by other Google services such as Gmail. This command does not take any path arguments.

Specific options

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

--drive-auth-owner-only

Only consider files owned by the authenticated user.

--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-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,odp.

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
epub	application/epub+zip	E-book format
html	text/html	An HTML Document
jpg	image/jpeg	A JPEG Image File
odp	application/vnd.oasis.opendocument.presentation	Openoffice Presentation
ods	application/vnd.oasis.opendocument.spreadsheet	Openoffice Spreadsheet
ods	application/x-vnd.oasis.opendocument.spreadsheet	Openoffice Spreadsheet
odt	application/vnd.oasis.opendocument.text	Openoffice Document
pdf	application/pdf	Adobe PDF Format
png	image/png	PNG Image Format
pptx	application/vnd.openxmlformats-officedocument.presentationml.presentation	Microsoft Office Powerpoint
rtf	application/rtf	Rich Text Format
svg	image/svg+xml	Scalable Vector Graphics Format
tsv	text/tab-separated-values	Standard TSV format for spreadsheets
txt	text/plain	Plain Text
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

--drive-impersonate user

When using a service account, this instructs rclone to impersonate the user passed in.

--drive-list-chunk int

Size of listing chunk 100-1000. 0 to disable. (default 1000)

--drive-shared-with-me

Instructs rclone to operate on your "Shared with me" folder (where Google Drive lets you access the files and folders others have shared with you).

This works both with the "list" (lsd, lsl, etc) and the "copy" commands (copy, sync, etc), and with all other commands too.

--drive-skip-gdocs

Skip google documents in all listings. If given, gdocs practically become invisible to rclone.

--drive-trashed-only

Only show files that are in the trash. This will show trashed files in their original directory structure.

--drive-upload-cutoff=SIZE

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

--drive-use-trash

Controls whether files are sent to the trash or deleted permanently. Defaults to true, namely sending files to the trash. Use --drive-use-trash=false to delete files permanently instead.

--drive-use-created-date

Use the file creation date in place of the modification date. Defaults to false.

Useful when downloading data and you want the creation date used in place of the last modified date.

WARNING: This flag may have some unexpected consequences.

When uploading to your drive all files will be overwritten unless they haven't been modified since their creation. And the inverse will occur while downloading. This side effect can be avoided by using the --checksum flag.

This feature was implemented to retain photos capture date as recorded by google photos. You will first need to check the "Create a Google Photos folder" option in your google drive settings. You can then copy or move the photos locally and use the date the image was taken (created) set as the modification date.

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.

Server side copies are also subject to a separate rate limit. If you see User rate limit exceeded errors, wait at least 24 hours and retry. You can disable server side copies with --disable copy to download and upload the files if you prefer.

Limitations of Google Docs

Google docs will appear as size -1 in rclone ls and as size 0 in anything which uses the VFS layer, eg rclone mount, rclone serve.

This is because rclone can't find out the size of the Google docs without downloading them.

Google docs will transfer correctly with rclone sync, rclone copy etc as rclone knows to ignore the size when doing the transfer.

However an unfortunate consequence of this is that you can't download Google docs using rclone mount - you will get a 0 sized file. If you try again the doc may gain its correct size and be downloadable.

Duplicated files

Sometimes, for no reason I've been able to track down, drive will duplicate a file that rclone uploads. Drive unlike all the other remotes can have duplicated files.

Duplicated files cause problems with the syncing and you will see messages in the log about duplicates.

Use rclone dedupe to fix duplicated files.

Note that this isn't just a problem with rclone, even Google Photos on Android duplicates files on drive sometimes.

Rclone appears to be re-copying files it shouldn't

The most likely cause of this is the duplicated file issue above - run rclone dedupe and check your logs for duplicate object or directory messages.

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 "ENABLE APIS AND SERVICES" search for "Drive", and enable the then "Google Drive API".
Click "Credentials" in the left-side panel (not "Create 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.
