Abstract
When execution of a write-back operation is selected, a storage system stores, in a cache area, data for which a write request is issued from a higher-level apparatus, stores an updated content of the cache area in a cache log storage area, and then writes the data to a data storage area. On the other hand, when execution of a write-through operation is selected, the storage system does not execute storage into the cache area and the cache log storage area, stores an updated content of the data storage area in a write log storage area, and then writes the data to the data storage area.
