RAID is not backup

Please note, this blog has been archived and now lives at www.discretecosine.com

Stumbled upon this article regarding a lawsuit filed against Promise Technology. It seems that online backup firm Carbonite was using Promise gear to store their data (mistake number one). They were relying strictly on RAID to keep the data safe (mistake number two). An alleged firmware bug caused the arrays to get trashed. So customers lost data, and Carbonite is suing Promise.

Just a good reminder that RAID Is Not Backup.

And another reason why you shouldn't trust Internet backup services, who could be run by amateurs (as Carbonite) or for all we know backing up to /dev/null.

Well, in truth, no backup is infallible so you can't put your trust in any of them - which is pretty scary.
