Reminds me back in the early 2000s I had a miniDV camcorder. There was a linux package which allowed you to write archives to the miniDV tapes over firewire, I think each small tape could hold about 12-13Gb which was quite impressive. The only downside is that it takes ~1hr to record and restore.
In the end I never stored any critical archives on that thing, as I suspected (correctly) that a number of years later I'd have no way to read them back.
