While reading some of the bloggs today i cam across this tip for you. Use your Web hosting companys hard drive as an off-site backup stroage center. http://www.tuaw.com/2007/04/02/backup-your-mac-to-dreamhost/
I have a few other ideas about this but will post them seperatly.
UPDATE:
Today on Lifehacker.com they did a reviw of some very good (and some free) back up utilites. This is very worthy of a look.
