SwiftBackupDriver.delete_object(container, object_name)¶: Deletes a backup object from a Swift object store.

SwiftBackupDriver.get_container_entries(container, prefix)¶: Get container entry names

SwiftBackupDriver.get_extra_metadata(backup, volume)¶: Swift driver does not use any extra metadata.

SwiftBackupDriver.get_object_reader(container, object_name, extra_metadata=None)¶

Return reader object.

Returns a reader object that retrieves a chunk of backed-up volume data from a Swift object store.

SwiftBackupDriver.get_object_writer(container, object_name, extra_metadata=None)¶

Return a writer object.
