pysync includes a pure-python implementation that will run on anything
that can run python, as well as a basic wrapper for librsync. It also
includes extension modules for md4sum and rollsum that speed it up a
Something possibly worth trying on it is psyco... it compiles python to
native code on the fly using a simple "import psyco". Pure python is a
bit slow compared to native C implementations, but psyco could help
close the gap a bit.
librsync is still under active development by myself and others, and
recently had a new release.
I haven't touched pysync for a while, but it should still work with the
latest librsync as the API hasn't changed. If there are any problems,
please let me know. I believe rdiff-backup also has a python wrapper for
librsync that might be more advanced than the one in pysync.
I have plans for both pysync and librsync, but I haven't worked on them
much lately. I find I am mostly motivated by feedback from others when
funding is not available :-)
