One of the major reasons why some companies don’t want to run a web load test on their production site is that they are not looking forward to performing activities such as the database back-ups and restores that a production site load test requires. We believe that such drills are a positive side-benefit of load testing. We have all heard stories of Web sites crashing under heavy load and taking many hours, or even days, to bring their system back.
Practicing system back-ups and recovery following a major load is an extremely important component of Web site preparedness. A load test on your production site will not only show you how well your system can handle a large load, but how well and how quickly your system and crew can recover from a site crash due to overload. If there are problems with post-crash recovery, the right time to discover and fix them is during a test, not while your site is experiencing real traffic peaks.
