A disaster recovery (DR) test is the examination of each step in a disaster recovery program, as outlined in the business continuity/disaster recovery (BCDR) planning process.
Disaster recovery testing helps ensure that an organization can recover data, restore business critical applications and continue operations after an interruption of services. The primary function of a DR test is to fully evaluate an organization's business continuity and disaster recovery plans. The testing process allows an organization to conduct plan maintenance and train staff about disaster recovery procedures.
Disaster recovery tests should be conducted on a regular basis. Communications, data recovery and application recovery are typically a focus of all disaster recovery testing. Other areas for testing vary, depending on the organization's recovery point (RPO) and recovery time (RTO) objectives.
