Here is the compilation of observations we have made about disaster recovery operations. Most of these were learned at the school of hard knocks. They are worth pondering.
Do not get creative and improvise during recovery. Trying something new usually fails.
Run the recovery like a military operation with battle-station positions and defined actions. When under fire, the roles and actions must be automatic.
The key roles are the Field General, the Diagnostician, and the Communicator. Choose these people carefully.
Restoring the system is as important as recovery. In other words, after switching to backups, restoring the primary system correctly must follow. Failing to do this right prolongs the perception of unreliability.
It is not recovered until the customer says it is recovered.
