Abstract: A storage system stores golden image of a server or any physical/virtual machine execution environment and associate the golden image and the storage port. The storage system also creates the copy of the golden image to the logical volume, and allocates the internal path between the storage port and the logical volume. Upon receiving an access request from the host computer via the storage port, the storage system transfers the access request between the storage port and the logical volume which stores the copy of golden image associated with the host computer.

Abstract: For a storage system which holds backup data of a first data storage extent in one or more second data storage extents in use of a first backup method, a backup status in a first backup method in a prescribed period is acquired and a first backup performance in a first backup configuration is computed based on this backup status. Meanwhile, a second backup performance in a second backup configuration is estimated based on a prescribed assumption in a prescribed period. Information is outputted based on the computed first backup performance and the estimated second backup performance.
