RAID is the zeroth-tier backup. At least it will prevent most of the horror stories where people accidentally destroy their backups when trying to restore them.

- arghwhat 8y agoNo. RAID allows you to combine make many highly fallible disks into one big less fallible disk. Making independent devices into a unified device is a concept that is the polar opposite to a backup. Your example is also why people say that two backups are needed. Once your live system fails, if you only had one backup, you are now left with none. What was a backup is now your only copy, leaving you very vulnerable.
