Abstract
When a power failure of a volatile first storage occurs, an apparatus detects the power failure, and writes backup target data in a non-volatile second storage. When an abnormality of the first storage occurs, the apparatus detects the abnormality, acquires second information including a hardware state at a time when the abnormality is detected, and writes the first information and the second information in the second storage. When an abnormality occurs during the writing the backup target data, the apparatus suspends the writing the backup target data, acquires the second information, and writes backup data and the second information in the second storage, where the backup data is the backup target data that has not been written to the second storage.
