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 The following configuration options are available for the Swift back-end backup driver. To enable the swift backup driver for 1.0 or 2.0 authentication version, specify 1 or 2 correspondingly. For example: backup_swift_auth_version = 2 In addition, the 2.0 authentication system requires 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 = per_user backup_swift_auth_version = 1 backup_swift_user = <None> backup_swift_key = <None> backup_swift_container = volumebackups backup_swift_object_size = 52428800 backup_swift_retry_attempts = 3 backup_swift_retry_backoff = 2 backup_compression_algorithm = zlib
