Provides backup, restore and delete of backup objects within Swift.

class SwiftObjectReader(container, object_name, conn)

Bases: object

read()
class SwiftObjectWriter(container, object_name, conn)

close()
write(data)
check_for_setup_errors()
delete_object(container, object_name)

Deletes a backup object from a Swift object store.

get_container_entries(container, prefix)

Get container entry names

get_extra_metadata(backup, volume)

Swift driver does not use any extra metadata.

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.

get_object_writer(container, object_name, extra_metadata=None)

Return a writer object.

Returns a writer object that stores a chunk of volume data in a Swift object store.

initialize()
put_container(container)

Create the container if needed. No failure if it pre-exists.
