摘要： Loads on a plurality of computers are made uniform after a fail over, and resource competition is prevented. Loads of nodes (1 to 4) in a cluster (100) are obtained, taking-over information when a trouble occurs in one of the plurality of nodes (1 to 4) is generated beforehand based on the obtained loads, and the taking-over information is stored in a shared storage system (6) shared by the plurality of nodes. The plurality of nodes (1 to 4) monitor operation states of one another. When an occurrence of a trouble is detected, each of the nodes (1 to 4) in the cluster (100) excluding the troubled node reads the taking-over information from the shared storage system (6), and takes over a processing of the troubled node based on a trouble pattern and the taking-over information.

摘要： Data is stored to a disk drive (4) in a directory path designated by a write request, and a directory path as a backup object and the directory path for the write request are compared with each other. When the directory paths match each other, the data is transferred to backup systems (3 and 5). In the case where the directory path for the write request is not the backup object, the data in the directory path is requested to be backed up when the directory path matches a preset condition.

摘要： This invention includes: a step (S1) of receiving a snapshot creation request from a client computer; a step (S3) of obtaining, upon reception of the snapshot creation request, a usage ratio of a second volume by the update differences; a step (S2) of obtaining a use history of the update differences in the second volume of the user; a step (S4, S5) of choosing, based on the usage ratio and the use history, one from differential snapshot in which the update differences of the first volume are written in the second volume and volume snapshot in which a third volume is synchronized with the first volume; and a step (S6, S7) of executing the chosen one of differential snapshot and volume snapshot. As a result, it is possible to economically use a differential volume by using differential snapshot in combination with volume snapshot.
