    • In the data processing system which maintains data duplication between sites having a host computer and a storage apparatus, transfer-data volume and cost in communication line between the sites are controlled and the load of both primary and secondary hosts is controlled, and a data update management function at the secondary site side is realized. In the primary site, a primary DKC of primary storage apparatus stores an update data in a primary side file when a primary user data is updated from a primary host. Being asynchronous with this update, a secondary remote copy program of a primary remote copy program and an intermediate processing section remote-copies and accumulates the update data in a secondary side file. A data reflection program of a secondary host reads the accumulated data and commands a secondary DKC of a secondary storage apparatus to reflect it on a secondary user data and stores the update information in a secondary log data.

    • A storage system 1 includes a first storage apparatus 100 and a second storage apparatus 100 communicatively coupled to an external apparatus 300. The first and second storage apparatuses respectively have first and second storage areas VDEVs selectively accessible from the external apparatus, first and second temporary storage areas 113, and remote copy controllers 1122 configured to control data copy process. The storage system includes a data I/O process authority information storage unit LDK storing data I/O process authority information.
