[Dirvish] Backing up Windows computers

I've recently written an open-source Windows program that creates a
volume snapshot using the Windows VSS service and then executes rsync.
This allows you to back up files that are kept open by other processes.

It also appears that recent cygwin sshd's have fixed the bug where rsync
over ssh hangs. So I can finally back up Windows computers to a dirvish
server using all free software.

My blog post describing it is:

The bitbucket project is:

The README on bitbucket goes into details of setting up sshd and
dirvish. Also on bitbucket are pre-built 32- and 64-bit versions with
.msi files.

I've run it on 75 GB backup sets with 55,000+ files without issue. But
if you find any problems, bug reports are welcome.
