Some books have turned up on amazon. What if you have multiple locations and you want to protect vCenter Server from a complete site failure?

This is the description of the book that is up on CreateSpace: Excellant news on the book. Protect vCenter Server within a site as you are much more likely to suffer a failure from hardware, network, or storage than a total site failure.
