not too long ago I did a flux image of a floppy, that floppy was required to boot a perfectly good cnc machine, and if it died, the machine would need its computer replaced (read: need to be replaced itself), the floppy drive was then replaced by a floppy emulator with a USB stick, and the guy now has two backups.
