Patent ID: 6859889

Claim:
A backup apparatus for performing backup for a remote information processing system operatively connected to the backup apparatus via a network the backup apparatus comprising: a fault detecting unit for detecting a fault generated in the remote information processing system; a backup system structure unit for structuring on the backup apparatus a backup system having a same system configuration as a system configuration of the information processing system in which the fault has been generated; a resource pool for storing a plurality of configuration resources for structuring the backup system; a resource management unit for selecting a configuration resource necessary for structuring the backup system having the same system configuration as the remote information processing system in which the fault has been generated, out of the plurality of configuration resources stored in the resource pool, and for assigning a selected configuration resource to the backup system, wherein the backup system structure unit structures the backup system by using an assigned configuration resource assigned by the resource management unit; wherein the backup apparatus performs backup for a plurality of remote information processing systems in each of which a corresponding fault has been generated, wherein the resource management unit selects the configuration resource for each of the plurality of remote information processing systems in each of which the corresponding fault has been generated, and assigns a selected configuration resource to the backup system for each of the plurality of remote information processing systems, and wherein the backup system structure unit structures a plurality of the backup systems to be corresponding to each of the plurality of remote information processing systems in each of which the corresponding fault has been generated, by using an assigned configuration resource assigned to the backup system for each of the plurality of remote information processing systems by the resource management unit.
