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.
