Yeah, and ordinarily I'd happily agree with you and not take a militant "raaaaaahh that's not a backup" stance, 'cause you're right, it is a backup of sorts. Unfortunately, for a lot of people, especially computer novices, "backup" is confused with "absolute guarantee against data loss", which forces me to occasionally say things that aren't 100% true in an engineering sense. If I say, "Well, RAID is kind of a backup, but...", people seem to stop listening just before "but".
