摘要:
A storage apparatus includes a backup processing unit that stores data stored in a first memory into a second memory as backup data upon occurrence of a power failure, a restore processing unit that upon recovery from the power failure restores the backup data backed up in the second memory to the first memory and erases the backup data, and an erasure processing termination unit that terminates the erasure processing upon a power failure occurring during erasure processing for erasing the backup data stored in the second memory, and a re-backup processing unit that re-backs up data in the first memory corresponding to the backup data erased from the second memory before the erasure processing is terminated by the erasure processing termination unit to a location in the second memory subsequent to a last location that contains the backup data which has not been erased.
