--- title: "Swift" description: "Swift" versionIntroduced: "v0.91" --- # {{< icon "fa fa-space-shuttle" >}} Swift Swift refers to [OpenStack Object Storage](https://docs.openstack.org/swift/latest/). Commercial implementations of that being: * [Rackspace Cloud Files](https://www.rackspace.com/cloud/files/) * [Memset Memstore](https://www.memset.com/cloud/storage/) * [OVH Object Storage](https://www.ovh.co.uk/public-cloud/storage/object-storage/) * [Oracle Cloud Storage](https://docs.oracle.com/en-us/iaas/integration/doc/configure-object-storage.html) * [Blomp Cloud Storage](https://www.blomp.com/cloud-storage/) * [IBM Bluemix Cloud ObjectStorage Swift](https://console.bluemix.net/docs/infrastructure/objectstorage-swift/index.html) Paths are specified as `remote:container` (or `remote:` for the `lsd` command.) You may put subdirectories in too, e.g. `remote:container/path/to/dir`. ## Configuration Here is an example of making a swift configuration. First run rclone config This will guide you through an interactive setup process. ``` No remotes found, make a new one? n) New remote s) Set configuration password q) Quit config n/s/q> n name> remote Type of storage to configure.

When you run through the config, make sure you choose `true` for `env_auth` and leave everything else blank. rclone will then set any empty config parameters from the environment using standard OpenStack environment variables. There is [a list of the variables](https://godoc.org/github.com/ncw/swift#Connection.ApplyEnvironment) in the docs for the swift library. ### Using an alternate authentication method If your OpenStack installation uses a non-standard authentication method that might not be yet supported by rclone or the underlying swift library, you can authenticate externally (e.g. calling manually the `openstack` commands to get a token). Then, you just need to pass the two configuration variables ``auth_token`` and ``storage_url``. If they are both provided, the other variables are ignored. rclone will not try to authenticate but instead assume it is already authenticated and use these two variables to access the OpenStack installation. #### Using rclone without a config file You can use rclone with swift without a config file, if desired, like this: ``` source openstack-credentials-file export RCLONE_CONFIG_MYREMOTE_TYPE=swift export RCLONE_CONFIG_MYREMOTE_ENV_AUTH=true rclone lsd myremote: ``` ### --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. ### --update and --use-server-modtime As noted below, the modified time is stored on metadata on the object. It is used by default for all operations that require checking the time a file was last updated. It allows rclone to treat the remote more like a true filesystem, but it is inefficient because it requires an extra API call to retrieve the metadata. For many operations, the time the object was last uploaded to the remote is sufficient to determine if it is "dirty". By using `--update` along with `--use-server-modtime`, you can avoid the extra API call and simply upload files whose local modtime is newer than the time it was last uploaded. ### 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 de facto standard (used in the official python-swiftclient amongst others) for storing the modification time for an object. ### Restricted filename characters | Character | Value | Replacement | | --------- |:-----:|:-----------:| | NUL | 0x00 | ␀ | | / | 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/swift/swift.go then run make backenddocs" >}} ### Standard options Here are the Standard options specific to swift (OpenStack Swift (Rackspace Cloud Files, Blomp Cloud Storage, Memset Memstore, OVH)). #### --swift-env-auth Get swift credentials from environment variables in standard OpenStack form.

Properties: - Config: tenant_id - Env Var: RCLONE_SWIFT_TENANT_ID - Type: string - Required: false #### --swift-tenant-domain Tenant domain - optional (v3 auth) (OS_PROJECT_DOMAIN_NAME). Properties: - Config: tenant_domain - Env Var: RCLONE_SWIFT_TENANT_DOMAIN - Type: string - Required: false #### --swift-region Region name - optional (OS_REGION_NAME). Properties: - Config: region - Env Var: RCLONE_SWIFT_REGION - Type: string - Required: false #### --swift-storage-url Storage URL - optional (OS_STORAGE_URL). Properties: - Config: storage_url - Env Var: RCLONE_SWIFT_STORAGE_URL - Type: string - Required: false #### --swift-auth-token Auth Token from alternate authentication - optional (OS_AUTH_TOKEN).

Properties: - Config: application_credential_id - Env Var: RCLONE_SWIFT_APPLICATION_CREDENTIAL_ID - Type: string - Required: false #### --swift-application-credential-name Application Credential Name (OS_APPLICATION_CREDENTIAL_NAME). Properties: - Config: application_credential_name - Env Var: RCLONE_SWIFT_APPLICATION_CREDENTIAL_NAME - Type: string - Required: false #### --swift-application-credential-secret Application Credential Secret (OS_APPLICATION_CREDENTIAL_SECRET). Properties: - Config: application_credential_secret - Env Var: RCLONE_SWIFT_APPLICATION_CREDENTIAL_SECRET - Type: string - Required: false #### --swift-auth-version AuthVersion - optional - set to (1,2,3) if your auth URL has no version (ST_AUTH_VERSION). Properties: - Config: auth_version - Env Var: RCLONE_SWIFT_AUTH_VERSION - Type: int - Default: 0 #### --swift-endpoint-type Endpoint type to choose from the service catalogue (OS_ENDPOINT_TYPE). Properties: - Config: endpoint_type - Env Var: RCLONE_SWIFT_ENDPOINT_TYPE - Type: string - Default: "public" - Examples: - "public" - Public (default, choose this if not sure) - "internal" - Internal (use internal service net) - "admin" - Admin #### --swift-storage-policy The storage policy to use when creating a new container. This applies the specified storage policy when creating a new container. The policy cannot be changed afterwards. The allowed configuration values and their meaning depend on your Swift storage provider. Properties: - Config: storage_policy - Env Var: RCLONE_SWIFT_STORAGE_POLICY - Type: string - Required: false - Examples: - "" - Default - "pcs" - OVH Public Cloud Storage - "pca" - OVH Public Cloud Archive ### Advanced options Here are the Advanced options specific to swift (OpenStack Swift (Rackspace Cloud Files, Blomp Cloud Storage, Memset Memstore, OVH)). #### --swift-leave-parts-on-error If true avoid calling abort upload on a failure. It should be set to true for resuming uploads across different sessions. Properties: - Config: leave_parts_on_error - Env Var: RCLONE_SWIFT_LEAVE_PARTS_ON_ERROR - Type: bool - Default: false #### --swift-chunk-size Above this size files will be chunked into a _segments container. Above this size files will be chunked into a _segments container. The default for this is 5 GiB which is its maximum value. Properties: - Config: chunk_size - Env Var: RCLONE_SWIFT_CHUNK_SIZE - Type: SizeSuffix - Default: 5Gi #### --swift-no-chunk Don't chunk files during streaming upload. When doing streaming uploads (e.g. using rcat or mount) setting this flag will cause the swift backend to not upload chunked files. This will limit the maximum upload size to 5 GiB. However non chunked files are easier to deal with and have an MD5SUM. Rclone will still chunk files bigger than chunk_size when doing normal copy operations. Properties: - Config: no_chunk - Env Var: RCLONE_SWIFT_NO_CHUNK - Type: bool - Default: false #### --swift-no-large-objects Disable support for static and dynamic large objects Swift cannot transparently store files bigger than 5 GiB. There are two schemes for doing that, static or dynamic large objects, and the API does not allow rclone to determine whether a file is a static or dynamic large object without doing a HEAD on the object. Since these need to be treated differently, this means rclone has to issue HEAD requests for objects for example when reading checksums. When `no_large_objects` is set, rclone will assume that there are no static or dynamic large objects stored. This means it can stop doing the extra HEAD calls which in turn increases performance greatly especially when doing a swift to swift transfer with `--checksum` set. Setting this option implies `no_chunk` and also that no files will be uploaded in chunks, so files bigger than 5 GiB will just fail on upload. If you set this option and there *are* static or dynamic large objects, then this will give incorrect hashes for them. Downloads will succeed, but other operations such as Remove and Copy will fail. Properties: - Config: no_large_objects - Env Var: RCLONE_SWIFT_NO_LARGE_OBJECTS - Type: bool - Default: false #### --swift-encoding The encoding for the backend. See the [encoding section in the overview](/overview/#encoding) for more info. Properties: - Config: encoding - Env Var: RCLONE_SWIFT_ENCODING - Type: MultiEncoder - Default: Slash,InvalidUtf8 {{< rem autogenerated options stop >}} ## 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. This may also be caused by specifying the region when you shouldn't have (e.g. OVH). ### Rclone gives Failed to create file system: Response didn't have storage url and auth token This is most likely caused by forgetting to specify your tenant when setting up a swift remote. ## OVH Cloud Archive To use rclone with OVH cloud archive, first use `rclone config` to set up a `swift` backend with OVH, choosing `pca` as the `storage_policy`. ### Uploading Objects Uploading objects to OVH cloud archive is no different to object storage, you just simply run the command you like (move, copy or sync) to upload the objects. Once uploaded the objects will show in a "Frozen" state within the OVH control panel. ### Retrieving Objects To retrieve objects use `rclone copy` as normal. If the objects are in a frozen state then rclone will ask for them all to be unfrozen and it will wait at the end of the output with a message like the following: `2019/03/23 13:06:33 NOTICE: Received retry after error - sleeping until 2019-03-23T13:16:33.481657164+01:00 (9m59.99985121s)` Rclone will wait for the time specified then retry the copy.
