Looking for cross-platform rsync-like functionality in python, such as rsync.py

I am implementing backup scripts in python. I'm trying to keep things cross platform. I hear ther开发者_如何学Goe is a python based rsync implementation: http://pypi.python.org/pypi/rsync.py

But I can't seem to find it anywhere. All of the download links I find are dead. Does anyone know where I could find the rsync.py program?

At the moment I am using unison for Windows but I would like to try rsync.py

Alternative : pysync - implementation of the rsync and related algorithms in pure Python, and a high speed librsync Python extension

Another alternative: http://code.google.com/p/pyrsync/

Here is the algorythm (not sure if it helps you out):

I know that rdiff-backup is written in python and use an rsync-like algorithm. It use librsync. Note that rdiff-backup is not a replacement for rsync, so it will not fill your needs. But you can take a look at librsync and see how rdiff-backup use it.

Here is another rsync implementation in Python:
