I've done this a few times.  Things go a little slowly on the initial 
transfer, but then things go fairly well.
In fact, the time i was running it, I was rsyncing over 140GB of data 
between two fileservers, in preparation for a switch.  Worked flawlessly.

If you're going to do this over a public network, be sure to check 
rsync's -e option.
  rsync -a -e ssh user at host:/path/to/source /path/to/destination
