I agree that it would be a frightening prospect to lose my hard drives however, thinking rationally, what am I more likely to lose? A few dozen pieces of papers of random level design sketches, or a hard drive with all of these images on it? A decent hard drive should last in excess of 5 years, and when I think about it those few dozen pieces of paper probably take a couple of weeks to fall behind a cupboard, under the desk, get thrown away and generally get lost/forgotten. Losing a hard drive/internet access is a frightening prospect, however the likelihood of some sort of event managing to knock out the internet and erase all hard drives is a lot lower then me losing pieces of paper, photo's and other physical media.
