it would be _really_ hard to find anything better than rsync. Both
because of safety (uses ssh by default) and efficiency (copies only
what's needed)

if you need point-in-time snapshots while the servers are running, the
simplest way is to do an LVM snapshot, mount it (as read-only) and
rsync from this to the remote server. afterwards simply destroy the
snapshot.

ok, forget about rsync. forget about how I get the data onto the order server. WHICH filesystem would be best for this type of operation? SMB, NFS, or iSCSI?
