No. If you backup runs in the early hours on a cron script and your drive fails at 6pm, not only have you lost a full day's work, but you'll spend the rest of the evening restoring your backups to a new drive. The next day you'll be tired and bleary-eyed, and still a day behind. With RAID1 (or 5), you just plug in another drive. RAID should not be considered an alternative to backups, but a separate layer of data security. > They even protect in > the event of theft or fire which RAID1 doesn't. Which is why you still need offsite backups. -- Neil Bothwick A closed mouth gathers no foot.
