Abstract
The management computer includes a memory and a processor. The processor recognizes a state of a storage system that provides a first volume as a logical volume that stores a first image of an object. The processor generates a second volume as a virtual logical volume that stores a second image of the object. The processor selects, based on the state, one generation processing from a plurality of generation processing including: first generation processing of associating the second volume with the first image and differential data from the first image to provide the second volume; and second generation processing of generating the second volume as a logical volume and copying the first image to the second volume to provide the second volume. The processor transmits an instruction to execute the selected generation processing to the storage system.
