Abstract

A data control system comprises a communication interface, a processing system, and a storage system. The communication interface is configured to receive a request to retrieve data from a primary storage volume that includes a secondary storage volume. The storage system is configured to store the primary storage volume that includes the secondary storage volume. The processing system is configured to identify changed segments of a plurality of segments in the primary storage volume and identify allocated segments of the changed segments. The communication interface is further configured to transfer the allocated segments in response to the request.
