Backup
(engine, hostname_backup_name, level_zero_timestamp, timestamp, level, storage=None)¶Bases: object
Internal freezer representation of backup. Includes:
name (hostname_backup_name) of backup
timestamp of backup (when it was executed)
level of backup (freezer supports incremental backup): Completed full backup has level 0 and can be restored without any additional information. Levels 1, 2, … means that our backup is incremental and contains only smart portion of information (that was actually changed since the last backup)
copy
(storage)¶engine_metadata
()¶get_increments
()¶Gets all incremental backups based on a level-zero backup with timestamp :rtype: dict[int, freezer.storage.base.Backup] :return: Dictionary[backup_level, backup]

Storage
(skip_prepare=False)¶Bases: object
Any freezer storage implementation should be inherited from this abstract class.
