摘要： A remote copy system includes a plurality of first storage systems and a plurality of second storage systems. Each first storage system assigns a sequential number to write data received from the host and sends the write data with the sequential number to the second storage system. One of the first storage systems defers the processing of the write request received from the host and instructs each of the first storage systems to create a marker, whereupon each of the first storage systems defers the processing of the write request, creates a marker including a sequential number and having a marker number, and sends the marker to the second storage system. Each of the second storage systems, when receiving a marker from the first storage system, stores the marker number included in the marker. One of the second storage systems reads the marker number stored by each of the second storage systems and determines if the marker numbers are the same. All write data sets having the same marker number are then stored in logical volumes of said second storage devices.

摘要： A storage system comprises a data set storage region or storing a data set containing data and update data for managing this data, and a control section. The data set storage region is divided into a plurality of storage regions including a first storage region and a second storage region. The control section generates a first data set containing first data and first update data which is update data for same, stores at least the first data of this first data set in the first storage region, generates a second data set containing second data and second update data which is update data for same, and stores at least the second data of this second data set in the second storage region, which is separate from the first storage region.

摘要： A data processing system includes a first storage system including a first host and a first storage subsystem. The first host has access to a first copy manager that is operable to manage a data replication operation. A second storage system includes a second host and a second storage subsystem. The second host has access to a second copy manager that is operable to manage a data replication operation. A first communication link is coupled to the first storage system and the second storage system to exchange management information between the first and second storage systems in order to manage the data replication operation. A data transfer path is configured to transfer data stored in the first storage subsystem to the second storage subsystem and replicate the data of the first storage subsystem in the second storage subsystem. The data transfer path is different from the first communication link.
