A storage device includes a control device that controls an access to storage, a volatile memory that stores data that is used for operation control of the control device, and a non-volatile memory is a backup destination of the data. Furthermore a storage device includes a detection unit that detects a failure occurred in the control device, a determination unit that determines whether or not backup data that is stored in the non-volatile memory is valid when the detection unit detects the failure occurred in the control device, and a control unit that causes the control device to execute a first processing of restoring the backup data of the non-volatile memory in the volatile memory after restart-up without backup of the data of the volatile memory, when the determination unit determines that the backup data of the non-volatile memory is valid. |
