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

Question

I am implementing backup scripts in python. I'm trying to keep things cross platform. I hear there 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

Solution 1

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

• http://freshmeat.net/projects/pysync/

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

Solution 2

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

Solution 3

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.

The second link you posted is actually just a wrapper for rsync. The first one, however, looks promising.

@AndyL: Thanks. I understand. I just thought it it is good to keep the various alternatives here as answer.

Thanks. The pysync README mentions windows binaries but I can't find them anywhere online. So instead I am following its instructions to compile from source. I run python setup.py bdist_wininst' and I get an error halfway through: error: Unable to find: vcvarsall.bat' :o/

@AndyL: If you have hit the biggest roadblock on compiling extension on windows. This file "vcvarsall.bat" is a batch file that sets up windows command line environment for compilers. Check out some SO discussion on this. You will have to determine your environment (Visual studio Version) and then check for the setup details.
