<P>PROBLEM TO BE SOLVED: To specify a data abnormality position in an information processing apparatus. <P>SOLUTION: The information processing apparatus 10 includes a connection unit 15 to which a separated backup storage device 20 can be connected; a data storing unit 13 that stores an objective data; and a processing unit 11 which backs up the data stored in the storage unit to the backup storage device. The processing unit 11 creates and accumulates a data change record which specifies data changed in the data storage part 13 after backing up the data stored in the data storage part to the backup storage device 20, detects a data difference part differed from the data stored in the backup storage device 20 of the data stored in the data storage part 13 in a state where the backup storage device 20 is connected, determines whether the data difference part is matched to the data change record, and identifies, when the data difference part is a mismatching data difference part mismatched to the data change record, that the mismatching data different part is abnormal data. <P>COPYRIGHT: (C)2009,JPO&INPIT |
