Yes, exactly.... You could use any mix of these things:
1) cygwin ssh + cygwin rsyncd
2) cygwin ssh + cygwin rsync
3) openvpn + cygwin rsyncd
4) openvpn + cygwin ssh + cygwin rsync
5) openvpn + winexe + cygwin rsyncd

probably more combinations also... Personally, I've used (and still use)
items 1, 2 and 5. I feel the best option right now is option 5, since it
allows to do shadow backups, it is secure (tunnel/vpn) and it also
enables compression over the wan (openvpn) as well as rsync bandwidth
optimisation.

I also configure local scripts which are scheduled on the windows
machine (usually cygwin bash scripts) to take the backup files produced
by various commercial software in use (multi-gigabyte files) and split
them (using cygwin split) into a large number of small files (depending
on the customer, between 20M and 100M files), then let backuppc backup
these small files. This allows for some small changes in a small number
of the files for backuppc to still do file level de-dupe on 90% of the
data (90% of the files contents do not change, the attrib files change
because the timestamp changes, but that doesn't matter).

Hope this helps....

Regards,
Adam
