Abstract

PURPOSE:To easily restore a file to its original state immediately before occurrence of a fault, even in case of a fault due to a user's error, which can not be recognized by a system, by designating a release time point of a faulty file by use of the data and time. CONSTITUTION:A deposit program 2 of a bank rewrites an account file in a user's file 3 in accordance with money receipt information from a terminal 1. Also, a log acquisition routine 4 stores a data Ai in an Ai data file 5 after updating whenever updating is executed. In this state, in case when an error is detected in a data inputted from the terminal 1, in order to release a user's file of the file 3, the data time is inputted to the system by use of an input card. As a result, a recovery routine 6 is operated, and an initial value is stored in an account file of a file 7. After that, the Ai data before the data time selected from the file 5 is read out in order, and is written in order to the account file of the file 7.
