I read an interesting paper in Science about backing up data to DNA as a future archive scenario. At the time I hadn't realized you could just store DNA by drying it out and putting it on an index card, I had visions of cryo vats of test tubes :-). Such a system would be a 'write once' sort of solution.

Indeed. That's exactly the kind of thing I'm talking about, although from what I've heard access times for DNA are still a bit steep though ;)
