I have been tasked with leading a project regarding updating a old and somewhat onesided disaster recovery plan. For now we're just looking at getting the IT side of DR sorted out. The last time they did this they set their scope by making up a single disaster (the data center flooded) and planning for it to the exclusion of all other disaster types. I would like to take a more well rounded approach. I know this is a solved problem, other organizations have written DR plans.
Our plan is to take our IT DR plan and go forward with it and say "Hey, this is what we want in a DR plan for IT, does it mesh with what the rest of the University is doing? Are there restored service priorties you'd like changed?" We have a pretty good idea what the rest of the plan is and we're expecting this to go over well.
What I am looking for is guidance on how to scope a DR plan and what questions I should be thinking about. Do you have favorite resources, books, training that are related to DR plan development?
