Bec, I have five 500gig external drives that back up (dual) all of our work each day at 1am. Our sites are backed up each week (after the main saturday update). All video is backed up to tape after it is transfered prior to editing and the photos are backed up to the drives and cds. The tapes and cds are taken from the safe to the bank once a month.

Backing up is not a problem once it becomes habit and our content can not be replaced if lost.
