Abstract:
A first storage system in one embodiment participates in a cycle-based asynchronous replication process with multiple additional storage systems. The first storage system establishes replication sessions with respective ones of the additional storage systems for replication of source data. For each of multiple cycles, the first storage system captures a snapshot of the source data for a current cycle, generates differential data between the snapshot and a corresponding snapshot for a previous cycle, and transmits the differential data to the additional storage systems in their respective replication sessions. In conjunction with completion of transmission of the differential data to a given one of the additional storage systems, the corresponding replication session determines whether or not a snapshot of the source data for a subsequent cycle is available. If there is no such snapshot available, the replication session triggers capture of the snapshot of the source data for the subsequent cycle.

Claim (Index 15):
A method comprising:\n establishing replication sessions in a first storage system with respective ones of a plurality of additional storage systems for replication of source data from the first storage system to each of the additional storage systems as part of a cycle-based asynchronous replication process; and for each of a plurality of cycles of the cycle-based asynchronous replication process, the first storage system: capturing a snapshot of the source data for a current cycle; generating differential data between the snapshot and a corresponding snapshot for a previous cycle; and transmitting the differential data to the additional storage systems in their respective replication sessions; wherein in conjunction with completion of transmission of the differential data to a given one of the additional storage systems in its corresponding one of the replication sessions, the method for that replication session further comprises:\n determining whether or not a snapshot of the source data for a subsequent cycle is available as a result of capture of the snapshot of the source data for the subsequent cycle having been previously triggered by another one of the replication sessions; and \n responsive to the snapshot of the source data for the subsequent cycle not being available, triggering capture of the snapshot of the source data for the subsequent cycle; \n wherein the method is implemented by at least one processing device comprising a processor coupled to a memory.
