The specific situation, defined priorities and the disaster recovery (DR) plan at hand will define how to perform your customer’s DR testing.

Keep in mind that redundancy has a huge impact on the DR exercise. For instance, the effort to rehearse failing over to a continuously updated redundant storage array in a secondary data center is relatively simple; in contrast, having no secondary array to fail over to requires restoring terabytes of data and rehearsing the loss of the data center itself. The DR testing efforts and costs associated with the two scenarios differ greatly, and companies need to do a thorough analysis before deciding whether to invest in redundancy or to pour money into a more elaborate rehearsal.
