Another person I know bet on RAID, and lost.

I just want to remind everyone out there who runs any sort of server or has important data that RAID is *NEVER* a substitute for proper backups.

RAID is only meant to improve reliability and uptime. In other words, a hard drive can fail and be replaced without bringing the system down. It will NOT protect against things like:

- Double disk failures (it happens! More often than you think.)
- Power surges frying the system
- User error (rm -rf * .tmp Aaww D'OH!!)
- and much more.

If you don't have a proper offline backup that is completely SEPARATE from your server, RAID or not, your data's days are numbered. It isn't a question of "if", but rather, "when".

DO NOT TRUST RAID TO KEEP YOUR DATA SAFE. ADOPT A PROPER BACKUP STRATEGY.

The time to do this, if you haven't, is yesterday. I'm serious.

Anyway, end rant. I just needed to remind everyone because I saw it happen yet again.
