What if EC2 is your failover solution? That seems like an ideal use case, considering the billing model. Keep one instance online at all times to clone the data, then spin up a few more to replace your servers when they die. Or just build what you need in two datacenters with load balancing between them, and accept that operating at half capacity for a while is a lot better than being down entirely.
