Patent ID: 10261719

Abstract:
Examples include volume and snapshot replication. In some examples, a user-initiated snapshot of a volume at a source array may be created, wherein the user-initiated snapshot has a pending status and the volume is a member of a set of volumes in a replication group. A synchronization snapshot may be created of the volume at a periodic synchronization time. The synchronization snapshot may have a pending status. Each snapshot of the volume may be stored at the source array and each snapshot may be recorded via a representative entry in an original snapshot list. The volume may be incrementally replicated to a target array such that the target array has a replica of the volume at the source array via a replication engine. Creation of a corresponding snapshot at the target array may be requested after each incremental replication of the volume such that each snapshot recorded in the original snapshot list is recreated and stored at the target array and the original snapshot list is recreated as a recreated snapshot list at the target array.
