A common trope in fantasy and science fiction is the ancient civilization whose vast knowledge was somehow lost to the ages. The idea resonates, because whether we’re conscious of it or not, we all know that knowledge is perishable. Not only do we forget things as individuals, but societies routinely lose vast quantities of information over time. Scholars estimate that 90% of texts from antiquity are now gone, and if you’ve ever tried to access an old computer file on a floppy disk, you know that we’re still actively losing access to old data.

One of the big problems facing whole-genome research efforts these days is archiving. A single experiment can generate a terabyte or more of data, and while it’s all conveniently stored on hard drives in the short term, that’s a poor medium for handing down the scientific heritage of mankind. The problem is twofold: digital data storage changes constantly, and many formats that were sold as “archival” have since turned out to be alarmingly perishable.
