Abstract
A computer-implemented method according to one embodiment includes receiving indication of a failure event at a primary location having a primary data storage volume. In response to receiving the indication of the failure event, data is restored in a secondary data storage volume located at a secondary location remote from the primary location. The restored data is copied to a supplemental data storage volume. A first set of data updates intended for the primary data storage volume are tracked using the supplemental data storage volume. A second set of data updates performed at the secondary data storage volume are tracked. The second set of tracked data updates is merged with the first set of tracked data updates and transitioned to the primary data storage volume in response to the primary data storage volume becoming available. An instruction is sent to resume data updates at the primary data storage volume.
