This morning we had some problems with the site involving a failed hard drive down at the data center. I have to say, this was quite a rude awakening after a pleasant Super Bowl Sunday!
Whether it's on a snazzy server or your home PC a hard drive can fail. It's easy to say "It won't happen to me". I'm glad we didn't say that! One good part of all of this is that we got to test out our backups, which performed swimmingly.
Another benefit of the debacle was the chance to move over to our new master database -- complete with a fancy RAID controller. RAID stands for Redundant Array of Inexpensive Disks. There are two disks there now, and the database is mirrored across them. If either drive fails, the other drive completely picks up the slack, we get a warning, and we can replace the broken one at our leisure. RAID gives us the ability to sleep easier in the future, and I'm glad to add it to the team.
Tonight, I'll drink to backups and RAID!

Mark glossed over the fact, but we use several additional backup methods and so no data was lost at all...
