Abstract
A information processing apparatus includes, upon instructing for writing back stored contents of a main memory unit to the stored contents of the main memory unit at the time of previous modification in a sequence number that is used for identifying whether write back to the main memory unit is needed, from a backup data stored in a backup memory unit, the sequence number stored in a sequence number memory unit. The information processing apparatus selects the backup data including an integrity verification data indicating that writing is carried out completely. The information processing apparatus extracts an original data and a write destination address included in the selected backup data and writes the original data, for each original data and the write address extracted from the backup data, to a storage area, of the main memory unit, indicated by the write destination address.
