You don't... the best long term format (practical) so far is optical - like
CDROMs, DVDROMs.  Longer lifespan than analog tape....

the nice thing about digital, if you have the time to do it, is if you make
bit-perfect backups, then you've 'reset the clock' on the lifespan,
something you can't do with analog.
