About recovery priorities
Your organization must decide between recovery cost (the infrastructure and testing) and the level of functionality that must be recovered. You may choose to recover only the most critical business functions immediately and then recover other functions later. Although all functions of an organization should be valuable and necessary for the organization to operate, it may be acceptable to operate at a reduced level for a specific period of time. The longer your organization can operate without a function, the easier and less expensive it becomes to recover that function. Therefore, given the higher cost of rapid recovery, only those functions that are required for immediate operation need to be recovered quickly. Delaying recovery of some functions can be a good business decision.
