Yes, using SFU/Interix works quite well as long as you deploy rsyncd (&
ssh tunnel) and not rsync over ssh, as the latter displayed the same
issues as did Cygwin (Interix rsync is v. 2.6 or so). The debian port of
Interix (see URL below) is the same as far as rsync goes and so offers
no advantage over the std Interix.

Also, remember to pay attention to the hotfixes as one or two are
recommended (NB the DEP one!) and what is what can be confusing.  See
http://www.debian-interix.net/hotfixes/ and
http://www.thinkers.org/~rodney/i_bugs.php for good summaries.

The key is to get SFU properly installed (do it as the REAL pc
Administrator account NOT any other with Administrator rights), install
openssh and rsync and get them set up, the former for shared key
authorization and the latter as a daemon, with a secrets file etc.
Thereafter, the backuppc bit is no different to any *nix box client.

I still run one client on Interix whilst others I have switched to
recent cygwin implementations because of the presence of rsync v 3.0.4
and associated improvements. CopSSh and CwRsync are two maintained
minimal footprint Cygwin implementations of openssh and rsync
respectively. See http://www.itefix.no/i2/copssh and
http://www.itefix.no/i2/cwrsync. A full Cygwin install is a little more
work getting openssh and rsync setup, but offers easy updating.

Aside of the problem with Interix and straight rsync, the only real
advantage of Interix over Cygwin is perhaps a modest speed advantage.

Thanks a lot for this detailed response and for all the invaluable insights. Will try this *and* Deltacopy on different machines.

Then there is also cwrsync as well. I have not yet used it with backuppc, but have used it for just rsyncing win boxes.
