I tend to use old hard drives for this sort of thing as well - typically btrfs-raid1 now (I like the checksumming, but if your archive format has such features probably not essential). If I only had 20GB, though, I'd probably use cloud storage. Amazon would only charge $0.20/mo for that on glacier, or not that much more for reduced-redundancy storage (which is cheaper to restore). I think the right choice depends on your disaster scenarios. The hard drive sitting in your closet is cheaper, but not so useful when your closet burns down in the same fire as your PC. -- Rich
