Selective copying of track data through peer-to-peer remote copy

A primary storage system, comprising:

• at least one primary storage device;
• at least one controller;
• an interface for a hardwire connection that is adapted to communicate data between the primary storage system and a secondary storage system;
• and
• logic integrated with and/or executable by the at least one controller, the logic being configured to:
• receive a request to establish a Peer-to-Peer Remote Copy (PPRC) relationship between the primary storage system and the secondary storage system;
• set a path between the primary storage system and the secondary storage system via the hardwire connection in response to receiving the request;
• receive a memory map;
• establish the PPRC relationship between the primary storage system and the secondary storage system in response to receiving the memory map;
• and
• copy, based at least in part on the memory map, one or more data tracks of the primary storage device to the secondary storage system without copying at least one other data track of the primary storage device to the secondary storage system;
• and
• wherein the one or more data tracks of the primary storage device comprise data tracks of a first characteristic, and
• wherein each other portion of the primary storage device comprises one or more data tracks of a second characteristic,
• wherein the data tracks of the first characteristic comprise valid data records, and
• wherein the data tracks of the second characteristic comprise empty data tracks.
