Abstract: A storage system in one embodiment comprises a plurality of storage devices and a storage controller. The storage system implements a loopback replication process in which one or more source storage objects are replicated to one or more corresponding target storage objects within the storage system. The storage system obtains a pairing identifier, pairs a source storage object with a target storage object by associating respective distinct instances of the pairing identifier with the source storage object and the target storage object, and replicates the source storage object to the target storage object based at least in part on the associated instances of the pairing identifier. Each of the source and target instances of the pairing identifier comprises a collision field. The collision fields of the source and target instances of the pairing identifier have respective distinct values in order to prevent collisions between the source and target storage objects during loopback replication.
