Abstract
An apparatus in an illustrative embodiment comprises at least one processing device that includes a processor coupled to a memory. The at least one processing device is configured to maintain for a first storage system a plurality of index tables characterizing data replicated between the first storage system and respective ones of at least two or more additional storage systems, to receive a request to replicate a particular data item between the first storage system and a designated one of the two or more additional storage systems, to access, responsive to the received request, a corresponding one of the index tables characterizing data replicated between the first storage system and the designated one of the two or more additional storage systems, and to control replication of the particular data item based at least in part on one or more entries of the corresponding one of the index tables.
