A storage system comprises a storage comprising a nonvolatile storage medium, and a storage control apparatus for inputting/outputting data to/from the storage. The storage control apparatus comprises a memory for storing management information, which is information used in inputting/outputting data to/from the storage, and a control part for controlling access to the storage. The control part stores the management information, which is stored in the memory, in the storage as a base image, and when the management information is updated subsequent to the base image being stored in the storage, creates a journal comprising information related to this update, and stores the journal in the storage as a journal group which is configured from multiple journals. |
