The backup driver for Swift back-end performs a volume backup to a Swift object storage system.
To enable the Swift backup driver, include the following
option in the cinder.conf
file:
backup_driver=cinder.backup.driver.swift
The following configuration options are available for the Swift back-end backup driver.
| Configuration option=Default value | Description |
| backup_swift_auth=per_user | (StrOpt) Swift authentication mechanism |
| backup_swift_container=volumebackups | (StrOpt) The default Swift container to use |
| backup_swift_key=None | (StrOpt) Swift key for authentication |
| backup_swift_object_size=52428800 | (IntOpt) The size in bytes of Swift backup objects |
| backup_swift_retry_attempts=3 | (IntOpt) The number of retries to make for Swift operations |
| backup_swift_retry_backoff=2 | (IntOpt) The backoff time in seconds between Swift retries |
| backup_swift_url=http://localhost:8080/v1/AUTH_ | (StrOpt) The URL of the Swift endpoint |
| backup_swift_user=None | (StrOpt) Swift user name |
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_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
