Rsync works great to back up directories over the Internet. For security I was interested in having the backup copy encrypted and rsync does not really work in this senario.
I use rdiff-backup over ssh to achieve reverse-differential incremental low-traffic remote backups. I actually sell the solution as a managed service to small business. I've been using it for 3 years now and it's rock solid.
However, you won't be able to have the backup copy encrypted because of the way the diff works.
