You, sir, are an idiot.  A complete and utter moron who should never again be allowed near a computer keyboard for fear of confusing it with your arse.  Why do I say this?

RAID IS NOT BACKUP, you miserable excuse for undifferentiated protoplasm!  It should never be considered backup, and anyone who uses those two terms interchangeably should be dropped into the Bog of Eternal Stench head-first.

RAID is data redundancy, guarding against certain types of hardware failure.  Backups guard against user stupidity - i.e. "Oh shit, I just deleted that payroll spreadsheet that the boss wants in two hours!"  The two are completely unrelated save that both of them are considered best practices.

Please, for the sake of true computer and computing intelligentsia internationally, find a different line of work.
