Abstract
An apparatus comprises a processing device configured to identify a set of asynchronous data replication sessions currently running on a storage system each associated with a corresponding recovery point objective, and responsive to determining that at least one of the asynchronous data replication sessions has a current synchronization time that exceeds its corresponding recovery point objective for a first iteration of a given time window, to compute a session weight for each of the asynchronous data replication sessions. The processing device is also configured to select, for a second iteration of the given time window, data for transmission from the asynchronous data replication sessions based at least in part on the computed session weights. The processing device is further configured to transmit, during the second iteration of the given time window, the selected data.
