    Uh, no. RAID is an entirely distinct concept from backing up your data, and RAID is never a replacement for backing up your data. The only benefit to RAID, is up-time.

    RAID does not protect you against hackers, user error, data corruption, viruses, fire, flood, theft, etc. A backup (stored off-site of course) does protect your data against all of these threats.

    The two concepts are complementary. Neither is a substitute for the other.
