Abstract: Exemplary embodiments for optimizing disaster recovery systems during takeover operations are provided. In one embodiment, by way of example only, a flag is set in a replication grid manager to identify replication grid members to consult in a reconciliation process for resolving intersecting and non-intersecting data amongst the disaster recovery systems for a takeover operation, including indicating those of the replication grid members that acquired ownership over cartridges belonging to source systems.

In one embodiment, by way of example only, a flag is set in a replication grid manager to identify replication grid members to consult in a reconciliation process for resolving intersecting and non-intersecting data amongst the disaster recovery systems for a takeover operation. The replication grid members are consulted for the takeover operation to accommodate a coordination of an ownership synchronization process for cartridges not distributed on-time to the replication grid members. Additional system and computer program product embodiments are disclosed and provide related advantages.

Abstract: Exemplary method, system, and computer program product embodiments for changing ownership of cartridges, such as virtual cartridges between remotely located virtual tape libraries, are provided. In one embodiment, by way of example only, processes and protocols for the changing ownership of the cartridges are controlled from a primary location to a secondary location. The production site is moved for the cartridges. The ownership of the cartridges is waived. Access is allowed to the cartridges. Additional data is written and replicated using resources of the cartridges.

Abstract: For coordinated disaster recovery, a reconciliation process is performed for resolving intersecting and non-intersecting data amongst disaster recovery systems for takeover operations. An ownership synchronization process is coordinated for replica cartridges via the reconciliation process at the disaster recovery systems. The disaster recovery systems continue as a replication target for source systems and as a backup target for local backup applications.
