I finally had someone straighten me out of RAID.  As we all know, RAID
provides a second drive that mirrors the first drive in real time.  The
issue is that if you totally screw-up a file and save it by mistake, RAID
will automatically mirror the screwed up file and you're left without a
backup.  The better arrangement is a system of backup disks that backup
every hour or once a day or whatever time schedule that you want to
establish.  Many folks have a primary drive backed up daily (or more often)
on a second drive and then a third drive that is kept offsite and backed up
once a month.  Some also do DVD backups to be kept offsite.
