Favorite Synchronizers for Win & Linux

I'm looking for a new file/directory synchronizer.
I've been using unison because it works on both windows and linux.

However, it often chokes on the very long directory paths and file names I encounter when backing up eclipse and eclipse workspace directories. I suppose one could argue that I should not be backing up eclipse directories because I could just download a new executable. However, when I get a eclipse implementation properly configured, I'd like to save it.

Can anyone recommend a synchronizer like unison that works for both windows and linux and long file names that can be run from a command line as well as a GUI?

Thanks,
Siegfried

Is there Windows support for rsync? Does that matter if you can SAMBA the files to be local to a LIUX system where you back them up?

You could try Delta Copy
google for it
