    Abstract: It has been impossible in prior art to copy every piece of data that is stored in a virtual volume. A management computer of this invention receives a copy request that designates a real storage area as a copy source, selects a virtual storage area that is associated with plural real storage areas as a copy destination virtual storage area, and judges whether or not a copy source virtual storage area and the copy destination virtual storage area are allocated to real storage areas. Based on a result of the judging, the management computer gives an instruction to copy data that is stored in the copy source real storage area to a copy destination real storage area, and keeps information about a replication relation between the copy source real storage area and the copy destination real storage area on which the data copy has been performed.

    Abstract translation: 现有技术中不可能复制存储在虚拟卷中的每一条数据。 本发明的管理计算机接收将真实存储区域指定为复制源的复制请求，选择与多个实际存储区域相关联的虚拟存储区域作为复制目的地虚拟存储区域，并且判断复制源 虚拟存储区域和复制目的地虚拟存储区域被分配给真实存储区域。 基于判断结果，管理计算机给出将存储在复制源真实存储区域中的数据复制到复制目的地实际存储区域的指令，并且保持与复制源实际存储区域和复制源实际存储区域之间的复制关系的信息 已经执行了数据拷贝的复制目的地实际存储区域。

    Abstract: The present invention provides a high-performance storage access environment to a user who moves around a wide area, while increasing the fault resistance of the system. A plurality of network storages (volumes) is assigned to the user. Then, at the occasion of logging in to a volume by the user, the volume that can be accessed with high performance from a position he made access is located. Addresses at a computer with which user makes access are associated with addresses of the volumes provided by a storage device in advance in an assigned volume management table so as to increase access performance. Then, a management server performs control so that the address of the volume associated with the user access position is returned as a response, at the time of logging in.

    Abstract: Provided is a computer system including a first storage subsystem and a second storage subsystem. The first storage subsystem has a first storage unit and a first control unit. The second storage subsystem has a second storage unit and a second control unit. The first control unit records journals, and identifies, when data stored in the first storage unit is to be migrated to the second storage unit, which ones of the recorded journals are related to the data that is to be migrated. The first control unit chooses the identified journals one at a time in reverse chronological order, and judges whether or not the chosen journal corresponds to a data update made at some point between a current time and a time that precedes the current time by a length of a journal retention term set for the second storage subsystem.

    Abstract: A first storage system includes a first storage area for storing data written by a computer. A second storage system includes a second storage area to which the data stored in the first storage area migrates. A third storage system includes a virtual storage area corresponding to the second storage area. An access request to the virtual storage area is converted into an access request to the second storage area to be issued. A management computer transmits, to the third storage system, an instruction to migrate the data of the second storage area to a third storage area of the third storage system based on a determination result between a value of the data migrated to the second storage area and a predetermined threshold value.
