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

Configuration

The initial setup for google cloud storage involves getting a token from Google Cloud Storage 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:

n) New remote
d) Delete remote
q) Quit config

Remote config
Use web browser to automatically authenticate rclone with remote?
 * Say Y if the machine running rclone has a web browser you can use
 * Say N if running rclone on a (remote) machine without web browser access
If not sure try Y. If Y failed, try N.
y) Yes
n) No
y/n> y
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

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 Google if using web browser to automatically authenticate. 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.

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

See all the buckets in your project

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 -i /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. 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.

Anonymous Access

For downloads of objects that permit public access you can configure rclone to use anonymous access by setting anonymous to true. With unauthorized access you can't write or create files but only read or list those buckets and objects that have public read access.

Application Default Credentials

If no other source of credentials is provided, rclone will fall back to Application Default Credentials this is useful both when you already have configured authentication for your developer account, or in production when running on a google compute host. Note that if running in docker, you may need to run additional commands on your google compute machine - see this page.

Note that in the case application default credentials are used, there is no need to explicitly configure a project number.

--fast-list

This remote supports --fast-list which allows you to use fewer transactions in exchange for more memory. See the rclone docs for more details.

Custom upload headers

You can set custom upload headers with the --header-upload flag. Google Cloud Storage supports the headers as described in the working with metadata documentation

• Cache-Control
• Content-Disposition
• Content-Encoding
• Content-Language
• Content-Type
• X-Goog-Storage-Class
• X-Goog-Meta-

Eg --header-upload "Content-Type text/potato"

Note that the last of these is for setting custom metadata in the form --header-upload "x-goog-meta-key: value"

Modification time

Google Cloud Storage stores md5sum natively. Google's gsutil tool stores modification time with one-second precision as goog-reserved-file-mtime in file metadata.

To ensure compatibility with gsutil, rclone stores modification time in 2 separate metadata entries. mtime uses RFC3339 format with one-nanosecond precision. goog-reserved-file-mtime uses Unix timestamp format with one-second precision. To get modification time from object metadata, rclone reads the metadata in the following order: mtime, goog-reserved-file-mtime, object updated time.

Note that rclone's default modify window is 1ns. Files uploaded by gsutil only contain timestamps with one-second precision. If you use rclone to sync files previously uploaded by gsutil, rclone will attempt to update modification time for all these files. To avoid these possibly unnecessary updates, use --modify-window 1s.

Restricted filename characters

Character	Value	Replacement
NUL	0x00	␀
LF	0x0A	␊
CR	0x0D	␍
/	0x2F	／

Invalid UTF-8 bytes will also be replaced, as they can't be used in JSON strings.

Properties:

• Config: token
• Env Var: RCLONE_GCS_TOKEN
• Type: string
• Required: false

--gcs-auth-url

Auth server URL.

Leave blank to use the provider defaults.

Properties:

• Config: auth_url
• Env Var: RCLONE_GCS_AUTH_URL
• Type: string
• Required: false

--gcs-no-check-bucket

If set, don't attempt to check the bucket exists or create it.

This can be useful when trying to minimise the number of transactions rclone does if you know the bucket exists already.

Properties:

• Config: no_check_bucket
• Env Var: RCLONE_GCS_NO_CHECK_BUCKET
• Type: bool

--gcs-decompress

If set this will decompress gzip encoded objects.

It is possible to upload objects to GCS with "Content-Encoding: gzip" set. Normally rclone will download these files as compressed objects.

If this flag is set then rclone will decompress these files with "Content-Encoding: gzip" as they are received. This means that rclone can't check the size and hash but the file contents will be decompressed.

Properties:

• Config: decompress
• Env Var: RCLONE_GCS_DECOMPRESS
• Type: bool
• Default: false

--gcs-endpoint

Endpoint for the service.

Leave blank normally.

Properties:

Limitations

rclone about is not supported by the Google Cloud Storage backend. Backends without this capability cannot determine free space for an rclone mount or use policy mfs (most free space) as a member of an rclone union remote.
