It's a giant topic. But, as with everything else SQL Server, start with the Books Online. Microsoft Developers Network (MSDN) also has an example of a plan. And finally you can always rely on Simple-Talk[/url] to have a few articles on any topic within SQL Server.

Those just scratch the surface of what's out there for this type of thing. They don't even get into using high availability and disaster recovery solutions from your SAN vendor. They don't cover some of the new HA & DR options with virtual machines either.

It's a HUGE topic. I won't be able to provide you with enough links here to provide a truly meaningful answer. I'm with the last post, what specifically are you after?
