Extended Remote Copy or XRC is an IBM zSeries and System z9 mainframe computer technology for data replication. It combines supported hardware and z/OS software to provide asynchronous replication over long distances. It is complementary to IBM's Peer to Peer Remote Copy service, which is designed to operate either synchronously or asynchronously over shorter distances.

XRC is also known as Global Mirror.

XRC is the z/OS copy services solution, and Global Mirror is the open systems solution. They are not the same.

Global Mirror utilizes asynchronous PPRC (peer to peer remote copy), while XRC is a synchronous operation.
