  • disaster recovery (DR)

    Disaster recovery strategies are critical, as many businesses fail following an unforeseen event. DR may require an internal or external site when a main data center is down.

  • disaster recovery (DR) test

    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.
