To avoid a disaster in a data warehouse it is very important not only to come up with a good backup startegy but also to test it extensively. The often forgotten cousin of the backup recovery world is backup testing. All too often, backup strategies are developed and never tested. In such a complex environment as a data warehouse the tendency is to put backup testing to one side while everything else is being tested. The general outcome is that backup never gets tested, or at best is tested only minimally.
