Disaster Recovery Plan (DRP) is a series of steps an enterprise will take to resume normal business operations following a disaster that disrupts business operations. A DRP is similar to a Business Continuity Plan (BCP) except that a DRP is specially concerned with the steps taken after the disaster has struck, and with post-disaster kinds of recovery.
Once a business has responded to a disaster by executing on previous plans for carrying on business functions, through a BCP, an DRP takes hold. It works to recover normal business operations that were lost or need to be reassessed such as data from vaults, employees' return to a normal worksite, and other non-emergency, non-contingency features of the business that were present before the disaster and its disruption.
“A thorough DRP includes steps for recovering and assembling an enterprise’s assets that might be shuttered in the event of a natural or man-made disaster. It includes plans for bringing the enterprise and all its resources back into the normal state that existed prior to the disruption.”
