Abstract
An apparatus in one embodiment comprises a first storage system having a plurality of storage devices. The first storage system is configured to participate in a replication process with a second storage system. The first storage system is further configured to identify a given data page to be replicated to the second storage system as part of the replication process, to obtain information characterizing compressibility of the given data page based at least in part on a compression process applied to the given data page in the first storage system, and to transmit the given data page in uncompressed form to the second storage system with the information characterizing compressibility of the given data page. The information characterizing compressibility of the given data page is utilizable by the second storage system to determine one or more characteristics of a compression process to be applied to the given data page in the second storage system.
