How do I keep my basement from flooding when a power outage shuts the sump pump off?

The heavy storms that have the potential to flood a basement, also have the the ability to cause prolonged power outages. If all you have is an electric sump pump, it will be put out of commission just when you need it most.
Sump pumps can also stop for a number of reasons including circuit breakers that trip, accidental unplugging, jammed switches, and mechanical failures. What happens to your basement then?
