ddar is a free de-duplicating archiver for Unix. Save space, bandwidth and time by storing duplicate regions of data only once.

For details, see the wiki.


Some pre-built packages are available.

Building from Source

For Debian/Ubuntu packages, just install build dependencies (see debian/control) and then run debuild as usual.

Other distributions: install protobuf, run make pydist and then python install.


Please submit contributions as pull requests on github, following these guidelines:

  • Maintain compatibility with Python 2.5.

  • Keep behaviour similar to ar(1) and tar(1) (principle of least surprise). Options, behaviour and formats that make sense to match should match as closely as possible.

  • The manpage should be the source of all knowledge. All options and behaviour should be documented there.

Something went wrong with that request. Please try again.
