What's the difference between testing and exercising in business continuity and disaster recovery?
If you're going to run a marathon, you exercise for several months before. You run, stretch, eat healthily, do sprints, burn fat, watch Chariots of Fire and so on. You're preparing your body and mind for a test. On the day, you hopefully finish the marathon. The discipline of exercise has improved your fitness, strengthened your mind and allowed you to pass the test.
