This is one of the major differences between digital and paper: digital requires constant upkeep.

If you'd replace the inscriptions on pyrymids and obelisks as well as the various old documents with their digital equivalent we'd have lost them long ago. And they will still be there long after their current digital equivalents have turned to dust. The only defense that digital has is boundless copies, in the hope that some of them survive. But the chances of any particular copy surviving very long is nil and even if it does it is probably going to be unreadable so you need to keep copying.
