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.drivers.swift
The following configuration options are available for the Swift back-end backup driver.
| Configuration option = Default value | Description |
|---|---|
| [DEFAULT] | |
| 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 = None | (StrOpt) The URL of the Swift endpoint |
| backup_swift_user = None | (StrOpt) Swift user name |
| swift_catalog_info = object-store:swift:publicURL | (StrOpt) Info to match when looking for swift in the service catalog. Format is: separated values of the form: <service_type>:<service_name>:<endpoint_type> - Only used if backup_swift_url is unset |
This example shows the default options for the Swift back-end backup driver.
