*Much* more information needed.
How much stuff? 50MB? 5GB? 500GB? 5TB?
How compressible is it? Text/MySQL files or MP3s and JPGs?
How important is it? Your own stuff, or a business' stuff?
How big of a window do you have to back it up? 30 minutes at 23:15,
and you're fired if it goes past midnight? All night between 17:30
How often will the lusers will "Michael, this stupid computer ate my
work. Bring it back!!" (Meaning, of course, that they
stupidly/carelessly deleted/overwrote it.) If it's a database, will
the developers want regular copies restored for testing?
Frequency? Nightly, weekly, every-other-day?
Retention? Keep backups for a month? Quarter? Year? 7 years?
Budget? Always a killer...
For a small business that has crucial data, I'd buy a bunch of
250/320/500GB drives and put them in firewire external enclosures.
Get a calendar and mark it Week 01 thru Week 53. With a Sharpie,
label the drives/enclosures:
Depending on how many weeks of retention you want, that's how many
letter of the alphabet you go up. Then, on the calendar next to the
week 01, write A
Week 02, write B
Week NN+1, write A.
That way I'd know which drive to use on which day.
As for backing it up, tar. Works like a champ.
