You don't need to set up an rsync _server_ at all.  So long as the rsync
program exists at each end (in Walt's case it's the same copy), the
remote end will run in _server_ mode.  rsync uses rsh commands to do the
network bit so it only needs rsh access to work.

Of course, rsh access accross the 'net is not a good thing so,
fortunately, rsync will (if asked) use ssh instead.  This is the preferred
option for rsync accross the internet.

BTW. It might be worthwhile having a look at mondoarchive

metal) most multi-disk configurations out there.  It handles RAID, LVM and
