I think there is supposed to be hard copies, too.
I was reading that RAID servers, the kind pretty anybody uses these days, are designed to not fail. If one hard drive does fail, it can be replaced as easily as you would put a toner cartridge in a printer.
Nothing gets lost, unless somebody makes it lost.
Only if they are printed out and not, shredded, burned, ashes strewn to the four corners of the world...
