Abstract
An apparatus comprises at least one processing device comprising a processor coupled to a memory. The at least one processing device is configured to initiate generation of a remote backup copy for a consistency group subject to replication from a first storage system to a second storage system, and responsive to receipt of a freeze indication from at least one application that utilizes the consistency group in the first storage system, to direct the first storage system to enter a write hold state. The at least one processing device is further configured to direct the second storage system to generate the remote backup copy from the consistency group as currently replicated from the first storage system to the second storage system, and responsive to receipt of a copy complete indication from the second storage system, to direct the first storage system to exit the write hold state.
