Back up and restore volumes
The cinder command-line interface
provides the tools for creating a volume backup. You can restore
a volume from a backup as long as the backup's associated database
information (or backup metadata) is intact in the Block Storage
database.
Run this command to create a backup of a volume:
$ cinder backup-create VOLUME
Where VOLUME is the name or ID of
the volume.
The previous command will also return a backup ID. Use this
backup ID when restoring the volume, as in:
$ cinder backup-restore backup_ID
As mentioned earlier, volume backups are dependent on the
Block Storage database. Because of this, we recommend that you
also back up your Block Storage database regularly in order to
ensure data recovery.
Alternatively, you can export and save the metadata of
selected volume backups. Doing so will preclude the need to
back up the entire Block Storage database. This is particularly
useful if you only need a small subset of volumes to survive a
catastrophic database failure.

backup metadata, see .
