    Abstract: Exemplary method, system, and computer program product 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. 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: Various embodiments for repository management in a data deduplication system, by a processor device, are provided. Metadata of an inode structure of an entire pre-allocated file system is captured, exported, and compressed from an existing deduplication appliance, the pre-allocated file system comprising a fully padded file system. The exported and compressed metadata of the pre-allocated file system is decompressed and imported into a data deduplication repository of a new deduplication appliance having an identical file system size as within the existing deduplication appliance, to initially configure or subsequently scale the inode structure of a file system of the data deduplication repository of the new deduplication appliance efficiently.

    Abstract: Subsequent to a storage operation performed on the source instance by a source component, a synchronization message is sent to a replicated component for the replicated instance. The synchronization message is stored locally in a persistent storage location associated with the source component along with an indicator representative of a time the storage operation was performed. Pursuant to receipt of the synchronization message by the replicated component, the replicated component is updated to a dirty state to indicate a lack of full synchronization between the source and replicated instances.

    Abstract: Various embodiments for disaster recovery (DR) production takeover in a computing environment by a processor device are provided. If, for a designated storage system operable in the computing environment, a takeover operation may be executed, and a DR storage system has validly replaced the designated storage system using a replacement process, a withdrawal of a DR mode of operation is performed, and ownership of at least one storage device operable in the computing environment is transferred to the DR storage system. The replacement process authorizes the DR storage system to transfer the ownership while withdrawn from the DR mode of operation.
