Consider using os.path.join(dirname, newsnapname)

I don't think it's a good idea to change that to path.join. Internally, even on Windows, bsync uses slashes everywhere - because it uses posix tools and because all snapshots contain slashes only. So using path.join at this place would be singular.
However, your remark suggests me that path.join should be removed on the remaining three places too, though it probably doesn't break anything, not even on Windows. I haven't tested bsync on Windows in ssh mode, so I cannot tell.

I made three commits:
bsync didn't work in Windows with the only rsync I've found (cwRsync). cwRsync doesn't recognise disk-letter colons, Bsync had similar problems with Windows. First commit fixes this.
bsync required that all conflicts were resolved immediately. In batch mode, bsync stopped on the first conflict. The second commit allows correct handling of unresolved conflicts - they are left for later bsync runs. This is also required for the third commit.
Third commit implements new uni-directional synchronization modes: backup and mirror (backup doesn't synchronize deletes). These modes correctly update bsync snaphots. Execution of bi-directional sync and uni-directional mirror and backup can be mixed without breaking the snapshots. Second commit is required.
I also added python unit tests of bsync of all tree modes.
Note: I tested that only locally in Windows, though I tried to keep it working in posix/ssh.
