Returning to your primary site
One aspect of disaster recovery planning which can be overlooked is the need to include plans for returning operations from the recovery site back to the primary site (or to a new primary site if the original primary site cannot be used again).
About this task
Build the return to normal operations into your plan. The worst possible time to create a plan for moving back to your primary site is after a disaster. You will probably be far too busy to spend time building a plan. As a result, the return to your primary site may be delayed, and may not work properly.
