I have a client that is asking how to have a hot site that will pick up if their website were to go out (say in an earthquake). I work on the web marketing side of things, so hosting/backup issues are not really my forte. But it would seem that this would be an ISP issue – having a mirrored site as part of the contract. Is this correct? If the current ISP doesn’t offer this as a service, other than moving to one that does, what would be an appropriate approach to setup such capabilities in the event of a disaster? Would one look into traditional IT hot site vendors such as Sungard?
