--- title: "Google Cloud Storage" description: "Rclone docs for Google Cloud Storage" versionIntroduced: "v1.02" --- # {{< icon "fab fa-google" >}} Google Cloud Storage 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 e/n/d/q> n name> remote Type of storage to configure. Choose a number from below, or type in your own value [snip] XX / Google Cloud Storage (this is not Google Drive) \ "google cloud storage" [snip] Storage> google cloud storage Google Application Client Id - leave blank normally. client_id> Google Application Client Secret - leave blank normally. client_secret> Project number optional - needed only for list/create/delete buckets - see your developer console. project_number> 12345678 Service Account Credentials JSON file path - needed only if you want use SA instead of interactive login. service_account_file> Access Control List for new objects.

Got code -------------------- [remote] type = google cloud storage client_id = client_secret = token = {"AccessToken":"xxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx","RefreshToken":"x/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx_xxxxxxxxx","Expiry":"2014-07-17T20:49:14.929208288+01:00","Extra":null} project_number = 12345678 object_acl = private bucket_acl = private -------------------- 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. 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](https://cloud.google.com/iam/docs/service-accounts), please head to the [Service Account](https://console.cloud.google.com/permissions/serviceaccounts) section of the Google Developer Console. Service Accounts behave just like normal `User` permissions in [Google Cloud Storage ACLs](https://cloud.google.com/storage/docs/access-control), 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](https://cloud.google.com/video-intelligence/docs/common/auth#authenticating_with_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](https://cloud.google.com/container-registry/docs/advanced-authentication#gcloud_as_a_docker_credential_helper). 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](/docs/#fast-list) 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](https://cloud.google.com/storage/docs/gsutil/addlhelp/WorkingWithObjectMetadata) - 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](https://cloud.google.com/storage/docs/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](/overview/#invalid-utf8), as they can't be used in JSON strings. {{< rem autogenerated options start" - DO NOT EDIT - instead edit fs.RegInfo in backend/googlecloudstorage/googlecloudstorage.go then run make backenddocs" >}} ### Standard options Here are the Standard options specific to google cloud storage (Google Cloud Storage (this is not Google Drive)). #### --gcs-client-id OAuth Client Id.

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-token-url Token server url. Leave blank to use the provider defaults. Properties: - Config: token_url - Env Var: RCLONE_GCS_TOKEN_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 - Default: false #### --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: encoding - Env Var: RCLONE_GCS_ENCODING - Type: MultiEncoder - Default: Slash,CrLf,InvalidUtf8,Dot {{< rem autogenerated options stop >}} ## 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. See [List of backends that do not support rclone about](https://rclone.org/overview/#optional-features) and [rclone about](https://rclone.org/commands/rclone_about/)
