Abstract
Provided are a method, system, and article of manufacture for using virtual copies in a failover and failback environment. Updates are copied from a primary first storage at the primary site to a secondary first storage at the secondary site during system operations. A second storage is maintained at at least one of the primary and secondary sites. A failover is performed from the primary site to the secondary site after a failure at the primary site. The at least one second storage is used after recovery of the primary site to synchronize the secondary site to the primary site. Only updates made to the secondary site during the failover are copied to or from the at least one second storage in response to the recovery at the primary site.
