Agreed 100%, home PC back-ups are not optional in this day and age. Our home computer contains pretty much the entire record of my 2-year-old's life in photo and video. If we lost that to a hard drive crash, I'd never forgive myself (not to mention what my wife would have to say).<p>With software like Time Machine, an on-site backup is nearly automatic, and I've had an archive up and running on a separate server for the past two years. My next step is putting together an off-site backup system, in case of fire, burglary or natural disaster. My plan is to buy a couple of spare drives and leave one at an out-of-state family member's house, rotating them out when we visit for holidays.
