Abstract:
In one embodiment, a computer-implemented method includes: receiving a request to establish a Peer-to-Peer Remote Copy (PPRC) relationship between a primary storage system and a secondary storage system; and copying one or more data tracks of a primary storage device in the primary storage system to the secondary storage system without copying at least one other data track of the primary storage device to the secondary storage system. The one or more data tracks of the primary storage device comprise one or more data tracks of a first characteristic. Other portions of the primary storage device comprise one or more other data tracks of a second characteristic. Tracks of the first characteristic may include valid data records, while tracks of the second characteristic may include invalid data records and/or empty tracks. Corresponding systems and computer program products are also disclosed.
