Swift backup driver

The backup driver for the swift back end performs a volume backup to an object storage system.

To enable the swift backup driver, include the following option in the cinder.conf file:

backup_driver = cinder.backup.drivers.swift.SwiftBackupDriver

The following configuration options are available for the Swift back-end backup driver.

cinder.backup.drivers.swift

To enable the swift backup driver for 1.0, 2.0, or 3.0 authentication version, specify 1, 2, or 3 correspondingly. For example:

backup_swift_auth_version = 2

In addition, the 2.0 authentication system requires the definition of the backup_swift_tenant setting:

backup_swift_tenant = <None>

This example shows the default options for the Swift back-end backup driver.

backup_swift_url = http://localhost:8080/v1/AUTH_
backup_swift_auth_url = http://localhost:5000/v3
backup_swift_auth = per_user
backup_swift_auth_version = 1
backup_swift_user = <None>
backup_swift_user_domain = <None>
backup_swift_key = <None>
backup_swift_container = volumebackups
backup_swift_object_size = 52428800
backup_swift_project = <None>
backup_swift_project_domain = <None>
backup_swift_retry_attempts = 3
backup_swift_retry_backoff = 2
backup_compression_algorithm = zlib
