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 as an z/OS copy services solution can be compared to Global Mirror, which is an open systems solution. Global Mirror utilizes asynchronous PPRC (peer to peer remote copy), while XRC is a synchronous operation.

In the first paragraph, this article says, it's asyncronous replication while in the second it mentions sychronous operation, please explain or correct.
