Better question: who knows if thiers works?

Skipping the politics, where I work, half the servers are at a central location. There is NO beta site, anywhere (politics). Back ups are made sporadically, and no one there knows how to use them to recover. They spent a bunch of money on a generator, instead.

Funny joke- when they loose power, the generator that they thought would turn itself on in 0-time doesn't turn on, period. The servers have about 45 minutes of APS, and the switches of squat.

And people wonder where my hair went.

Let this serve as two lessons:
-Have Plan B ready to go just as fast as you do Plan A, and Plan C on warm standby.
-Read the manual, before you need it.
