STORAGE SYSTEM, CONTROL APPARATUS, AND METHOD FOR CONTROLLING STORAGE SYSTEM

A storage system includes a library apparatus, a storage apparatus, and a control apparatus including a processor. The processor is configured to execute a copy processing of copying data of a plurality of logical volumes from a storage apparatus to a first recording medium. The copy processing includes a read processing of reading first data of a first logical volume from the storage apparatus, and a first write processing of writing the first data to the first recording medium. The processor is configured to execute a second write processing of writing second data of the first logical volume to the storage apparatus. The processor is configured to interrupt the first write processing and execute the second write processing in a case where a conflict occurs between the second write processing and the first write processing, and resume the copy processing from a leading part of the first logical volume.
