1. A method comprising:
maintaining a remote copy relationship between a local computational device and a remote computational device for a first storage volume and a second storage volume; and
transmitting, by the local computational device to the remote computational device, information indicating that there are no deduplication matches between the first storage volume and the second storage volume in the local computational device, 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.
