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: http://www.synctus.com/ddar/.
Some pre-built packages are available.
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 setup.py install.
Please submit contributions as pull requests on github, following these guidelines:
-
Maintain compatibility with Python 2.5.
-
Keep behaviour similar to
ar(1)andtar(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.
