Hm. you've got me thinking now...

>From what I know, rsync uses ssh by default. This was changed from rsh 
some years back. You can force rsh with the -e or --rsh parameters - but 
that means setting up rsh. So if you just use rsync, then it will be using 
ssh already.

However, there is a mode whereby the remote site can run an rsync daemon, 
but even then I think it still needs some sort of transport module - ie 
ssh, but I've just glossed over the man page without really taking much 
in. I know what works for me ;-)

tar piped into ssh (or rsh!) is even faster - I sometimes use that for the 
first initial copy. Actually, I have a copy of a 100GB container to do 
this weekend between 2 hosts on 100Mb networking. I'll run some tests :)
