Abstract
Methods, systems, and computer program products for providing deferred replication of recovery information at site switchover are disclosed. A computer-implemented method may include receiving a first copy of logged data for storage volumes of a disaster recovery (DR) partner at a remote site from the DR partner, receiving a request to perform a site switchover from the remote site to the local site, receiving a second copy of logged data for the storage volumes from a local high availability (HA) partner in response to the switchover, and recovering the storage volumes locally by applying one or more of the copies of logged data to corresponding mirrored storage volumes at the local site.
