I think you should think out of the box here. You didn't ask the right questions.

How can you make people don't email you every time when they have problems? Like building a good knowledge database .... give them the solution of the problem before they asked for it and so on.

How can you prevent the disaster strikes to be less then a minimum and hopefully never to happen?

For does question the right answers depends on you and what you can find on the net ....I think.
