摘要： In a cluster-structured disk subsystem, when creating a volume for an online backup separately from a volume for a normal I/O, it is desirable to be able to achieve such a creation for any volume under subsystem. Further, with an increase in the capacity of the subsystem, it becomes more difficult for a user to determine where to place a volume to which data is to be copied. Thus, a cluster-structured storage system is provided in which it is possible to reference/renew snapshot control information in shared memory of other clusters and achieve a snapshot between clusters via an inter-cluster connecting mechanism. In this system, control is performed inside/outside the cluster, and a control is performed inside/outside the cluster, and a volume to which data is to be copied is suggested to the user.

摘要： In a computer system that includes a first computer, a second computer, a first storage apparatus storing data in a fixed-length block format used by the second computer, and a backup apparatus connected to the first computer and storing data in a variable-length block format, the present invention provides a backup method for backing up data stored in the first storage apparatus to the backup apparatus. The first computer sends the second computer a request to read data in the fixed-length block format. In response to this request, the second computer reads the fixed-length block format data from the first storage apparatus and transfers this data to the first computer. The first computer converts the transferred fixed-length block format data into variable-length block format data. The converted variable-length block format data is stored in the backup apparatus.
