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.
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)
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.
