Explanation
DR test types range from least to most disruptive in this order: (1) Checklist Review, (2) Structured Walk-Through (Tabletop), (3) Simulation, (4) Parallel Test, (5) Full Interruption Test. A Full Interruption test is the most complete and realistic because the primary site is actually shut down and all operations are transferred to the alternate/recovery site - exactly as would happen in a real disaster. It is performed last because it carries the highest risk of business disruption. A Parallel test (the step before) runs both sites simultaneously, so there is no risk of losing production; a Full Interruption test removes that safety net.
