Abstract: The storage system including a first disk array apparatus for providing first volumes for storing data sent from a host system; a second disk array apparatus for providing second volumes for storing back-up data of the first volumes; and a console terminal for operating the first disk array apparatus. The console terminal is equipped with a setting unit for setting a priority for each first volume in accordance with an external command. The first disk array apparatus is equipped with: a storage unit for storing the priorities set by the priority setting unit; and a transfer unit for reading the priorities from the storage unit upon receiving the data and transferring the data stored in the first volumes to the second volumes of the second disk array apparatus in order of descending priority of the first volumes that store the data.

Abstract: Embodiments of the present invention are directed to methods and systems of storing data in storage volumes while ensuring data matching between the storage volumes. In one embodiment, a system for storing data comprises a first storage area to store data, a second storage area to store data, a first storage control unit configured to control the first storage area, and a second storage control unit configured to control the second storage area. In response to a first write request issued to write data in the first storage area, the first storage control unit is configured to write data associated with the first write request to the first storage area and to transfer the first write request to the second storage control unit, and the second storage control unit is configured to write the data associated with the first write request to the second storage area.

Abstract: The present invention suggests a storage system capable of realizing highly reliable data back-up. The storage system includes: a first disk array apparatus for providing first volumes for storing data sent from a host system; a second disk array apparatus for providing second volumes for storing back-up data of the first volumes; and a console terminal for operating the first disk array apparatus.
