any time you buy 1 disc, buy 2. The second is for backup.

The major fallacy in that solution is that you're treating redundancy and
backup equally. RAID doesn't protect you from a horked partition table,
accidentally deleted file, or blown up power supply. In my mind, RAID is for
data that you'd like some level of protection on but can lose, whereas a
true backup solution is for data you just can't lose. Of course, a
combination of the two is the most ideal approach for the most important
data.
As for the backup solution, I think the only real answer is RAID. A
good RAID 5 setup will do the job nicely as long as you have a good
controller and a UPS. If you want to get really secure a RAID 50
setup on independent power circuits should do the trick.
