Abstract
A remote copy relationship is maintained between a local computational device and a remote computational device for a first storage volume and a second storage volume. The local computational device transmits information to the remote computational device, wherein the information indicates that there are no deduplication matches between the first storage volume and the second storage volume in the local computational device, and wherein the remote computational device is configured to avoid scanning for deduplication matches between a remote copy of the first storage volume and a remote copy of the second storage volume based on the information that is transmitted.
