Backshift is a deduplicating backup program with compression and expiration, written in Python.

Its source code can be checked out from here, or you can download a tarball from here.

Here is the project's documentation

Very brief comparison with rsync -- see also this comparison.

Backshift is not just another tar frontend. Saved data is stored in an open but created-for-the-purpose, highly compressed format that can be assembled into a tar archive to stdout on request.
