Multi-Storage System Replication Utilizing Coordinated Dataset Checkpoints

A method comprising:

• replicating, from a plurality of source storage systems to a plurality of target storage systems, a plurality of local source checkpoints that are associated with a coordinated source checkpoint representing a snapshot of a source dataset stored across the plurality of source storage systems;
• and
• creating, based on the replicated plurality of local source checkpoints, a coordinated target checkpoint for a replica of the source dataset that is stored across the plurality of target storage systems.

An apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to:

• replicating, from a plurality of source storage systems to a plurality of target storage systems, a plurality of local source checkpoints that are associated with a coordinated source checkpoint representing a snapshot of a source dataset stored across the plurality of source storage systems;
• and
• creating, based on the replicated plurality of local source checkpoints, a coordinated target checkpoint for a replica of the source dataset that is stored across the plurality of target storage systems.

A computer program product disposed upon a computer readable medium, wherein the computer readable medium is not a signal, the computer program product comprising computer program instructions that, when executed by a processor, cause a computer to:

• replicating, from a plurality of source storage systems to a plurality of target storage systems, a plurality of local source checkpoints that are associated with a coordinated source checkpoint representing a snapshot of a source dataset stored across the plurality of source storage systems;
• and
• creating, based on the replicated plurality of local source checkpoints, a coordinated target checkpoint for a replica of the source dataset that is stored across the plurality of target storage systems.
