I agree (unless we have a nuclear war). But, if saving your data is REALLY important, I would add a couple suggestions:

Try to make file copies where the copied data is verified. I don't know about Windows, but in DOS, if you are in the source directory and are copying all MIDI files, use the "/V" option: COPY *.MID A: /V. The "/V" option verifys the written data is the same as the source.

Make at least two copies and send one set to your out-of-state relatives. I live in San Francisco, so I don't even trust my neighborhood bank vault.
There was an earlier submission that worried about the earth's magnetic field - I would worry more about fire. Although Ibelieve that extreme heat can change magnetic fields - long before that time, the disk is melted. Even paper fire safes or file cabinets don't guarantee magnetic media. You need a "data" fire safe. Mailing multiple copies is much cheaper.

(If we don't have trustworthy relatives, maybe we can mail everything to Jody?)

[ Editor's Note: I got a chuckle out of that. I'd _LOVE_ to archive
[ everyone's Roll and MIDI data. I won't promise not to listen to it, though ;-)
[ That thing at the end of the last line is a "winking smiley-face".
[ The truth is that I try to keep half of my backups in a safe deposit box at
[ the bank. Its expensive, and inconvenient, but it seems unlikely that
[ bank and my house will burn down on the same day.
