Swift backup driver

Icehouse - Icehouse - Icehouse - Icehouse - Icehouse - Icehouse - Icehouse - Icehouse -

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.

Table 1.32. Description of configuration options for backups_swift
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 = 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
