Abstract
Methods, apparatus, and processor-readable storage media for tracking data mirror differences are provided herein. An example computer-implemented method includes obtaining a request to start tracking data differences between a plurality of data mirror volumes of a storage system, wherein the storage system is configured to apply at least a first data tracking technique that tracks the data differences using one or more bitmap records and a second data tracking technique that tracks the data differences using or more journal records; selecting at least one of the first data tracking technique and the second data tracking technique using one or more selection criteria; and tracking the data differences in accordance with the selected at least one data tracking technique.
