Great feedback, everyone!   It's true, there are lots of things to consider (setting expectations is a good example), and then again considering everything isn't always the best approach.  I've seen companies go all out on a comprehensive DR/BC plan, spending hundreds of thousands of dollars to cover every angle -- even when the overall risk is fairly low. 

I think Steve makes a great point -- having a DR plan that attempts to encompass every possibility just isn't practical for most companies.  The key is getting everyone involved, make sure everyone understands risks and the consequencies for any given scenario.

I've got more coming on DR/BC and backup in general.  I'd really like to keep the discussion going!
