metadata aside (which I don't really care about) data is much more 
important - rdiff-backup on cygwin can do --list-increments, ie can 
output stuff, but then you try and do a --restore or --compare, it 
complains about metadata not existing and exits. So there is some bug in 
the admittedly unstable series that prevents it writing back to the file 
system. 0.12.5 doesn't have this problem. tho 0.12.5 doesn't have any fs 
detection features, which are pretty useful when it comes to disabling 
fsyncs. so 0.12.5 works, but crashes after it tries to fsync things.

The solution is out there somewhere - I haven't taken apart the code, 
and the guy I had working on it go distracted by the web interface. The 
web interface is now finished, but its for a client so until the client 
permits us to open a part of it, we can't release any of it.
it would probably take a skilled python programmer with access to a 
windows machine and a copy of my package only a day or two of debugging 
to figure it out.

please let me know how you go with that package. I have had very little 
feedback.
