haven't done much experimenting with this; but tar over nfs ought to be
pretty quick. (also pretty insecure, and occasionally prone to
causing other headaches as nfs is wont to do).

I think I've heard of a patch you can apply to remove encryption entirely;
but here's a sample option I'm using on a really low-bandwidth link;
$Conf{RsyncClientCmd} = '$sshPath -C -o CompressionLevel=9 -c blowfish-cbc
-q -x -l rsyncbakup $host $rsyncPath $argList+';
I would guess that for a high-bandwith connection, the blowfish-cbc cipher
may still provide some benefit; but you could try setting CompressionLevel
to 0 or 1 (or some other small value) and see if that improves your speed.

no. rsync is rsync; it's just a matter of whether there's a daemon already
listening (rsyncd), or whether it gets started by the ssh connection
(ssh+rsync).
