Claim 7:
8. A non-transitory computer-readable storage medium embodying a set of instructions, which when executed by one or more processing resources of a distributed storage system, cause the distributed storage system to:
maintain state information regarding a data replication status of a mirror copy of a dataset associated with a local consistency group, wherein the distributed storage system includes a plurality of volumes that are members of the local consistency group and wherein the mirror copy is stored on a corresponding plurality of volumes that are members of a remote consistency group of a remote distributed storage system;
responsive to a predetermined event, after a period of time during which the state information indicated each volume of each volume pair of a plurality of volume pairs including a volume of the plurality of volumes of the local consistency group and a corresponding volume of the remote consistency group was in an out-of-synchronization (OOS) state, create a baseline snapshot of the dataset in a dependent write-order consistent manner;
transfer the baseline snapshot to the remote distributed storage system; and
bring the mirror copy into an in-synchronization (InSync) state by, for each volume pair of the plurality of volume pairs, orchestrating a resynchronization of the volume pair independent of any other volume pair of the plurality of volume pairs and in parallel with one or more other volume pairs of the plurality of volume pairs.
