Data Recovery Tales: RAID Is Not Backup

[Terry Kennedy]

I've repeatedly (and unsuccessfully) tried to convince others that RAID is not a backup solution - for example, this thread over on the FreeBSD forums, which I started over 2 years ago.

Today I happened to be browsing blu-ray.com and the lead article is titled "Database Loss". I'll paste the lead paragraphs of that article below, but click on the above link for the whole thing.

Perhaps reading the article will help convince people that RAID is Not Backup. Perhaps not. If it does manage to convince you, good.

We are extremely sad to let you know that we've experienced 7 weeks of database loss. 7 weeks ago we moved to a new much improved server, but unfortunately earlier today the hard drives of the database crashed (was using RAID). On the old server we did daily backups, but since we changed server and setup, the old server backup solution didn't work anymore. We have been discussing the new backup system on a daily basis, but hadn't yet implemented it, so the timing couldn't have been worse.
