<i class="fa fa-space-shuttle"></i>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://cloud.oracle.com/storage-opc)
  * [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, eg `remote:container/path/to/dir`.

Here is an example of making a swift configuration.  First run

    rclone config

This will guide you through an interactive setup process.

Remote config
--------------------
[test]
env_auth = true
user = 
key = 
auth = 
user_id = 
domain = 
tenant = 
tenant_id = 
tenant_domain = 
region =

auth_token = 
auth_version = 
endpoint_type = 
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```

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

See all containers

    rclone lsd remote:

Make a new container

    rclone mkdir remote:container

List the contents of a container

    rclone ls remote:container

Sync `/home/local/directory` to the remote container, deleting any
excess files in the container.

    rclone sync /home/local/directory remote:container

### Configuration from an OpenStack credentials file ###

An OpenStack credentials file typically looks something something
like this (without the comments)

```
export OS_AUTH_URL=https://a.provider.net/v2.0
export OS_TENANT_ID=ffffffffffffffffffffffffffffffff
export OS_TENANT_NAME="1234567890123456"
export OS_USERNAME="123abc567xy"
echo "Please enter your OpenStack Password: "
read -sr OS_PASSWORD_INPUT
export OS_PASSWORD=$OS_PASSWORD_INPUT
export OS_REGION_NAME="SBG1"
if [ -z "$OS_REGION_NAME" ]; then unset OS_REGION_NAME; fi
```

The config file needs to look something like this where `$OS_USERNAME`
represents the value of the `OS_USERNAME` variable - `123abc567xy` in
the example above.

```
[remote]
type = swift
user = $OS_USERNAME
key = $OS_PASSWORD
auth = $OS_AUTH_URL
tenant = $OS_TENANT_NAME
```

Note that you may (or may not) need to set `region` too - try without first.

### Configuration from the environment ###

If you prefer you can configure rclone to use swift using a standard
set of OpenStack environment variables.

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.

        - 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.

- Config:      storage_policy
- Env Var:     RCLONE_SWIFT_STORAGE_POLICY
- Type:        string
- Default:     ""
- 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, Memset Memstore, OVH)).

#### --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 5GB which is its maximum value.

- Config:      chunk_size
- Env Var:     RCLONE_SWIFT_CHUNK_SIZE
- Type:        SizeSuffix
- Default:     5G

#### --swift-no-chunk

Don't chunk files during streaming upload.

When doing streaming uploads (eg 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 5GB. 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.

- Config:      no_chunk
- Env Var:     RCLONE_SWIFT_NO_CHUNK
- Type:        bool
- Default:     false

#### --swift-encoding

This sets the encoding for the backend.

See: the [encoding section in the overview](/overview/#encoding) for more info.

- Config:      encoding
- Env Var:     RCLONE_SWIFT_ENCODING
- Type:        MultiEncoder
- Default:     Slash,InvalidUtf8

<!--- autogenerated options stop -->

### 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 defacto 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.

### 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 (eg OVH).

#### Rclone gives Failed to create file system: Response didn't have storage storage url and auth token ####

This is most likely caused by forgetting to specify your tenant when
setting up a swift remote.
