Hitachi TrueCopy, formerly known as Hitachi Open Remote Copy (HORC) or Hitachi Remote Copy (HRC) or Hitachi Asynchronous Remote Copy (HARC), is a remote mirroring feature from Hitachi storage arrays available for both open systems and IBM z/OS. Truecopy is an implementation of IBM's PPRC protocol.
Synchronous TrueCopy causes each write to the primary volume to be performed to the secondary as well, and the I/O is considered complete only when updates to both primary and secondary have completed. Asynchronous TrueCopy stores time-stamped IO packets in the primary disk array and transfers them to the secondary array subject to link bandwidth. When the primary array's buffer is exhausted, it starts flagging tracks on the primary to be duplicated to the secondary when bandwidth permits.
