This subject has been discussed quite a bit already but one detail that hasn't really been addressed all that much is actually one of the most basic -and applies to your recent situation, and that is information.

In other words, one of the biggest things is to KNOW the power has gone out. Had you known, perhaps you could have called someone to go and start that generator.

So perhaps some way of being advised by SMS or such if there is a power failure would be the most valuable 'backup' you could have.

Of course, you need to have someone who can get into your house, connect and run a generator and preferably has reef experience. I guess that means you need a 'disaster plan' so that the person doing this for you is prepped and knows how to do all this and isn't figuring it out on the fly.
