Abstract
Dump data of a memory is allowed to be easily and appropriately managed. In a storage apparatus including a CPU, a DRAM, and a drive, the CPU executes storage processing to store data of the DRAM to be stored into the drive as dump data upon a failure occurrence in the storage apparatus. The CPU deduplicates the dump data in the storage processing or after storing the dump data into the drive. The CPU may execute deduplication processing between the dump data and other dump data stored in the drive or may execute deduplication processing within the data to be stored.
