PURPOSE:To make file restoration processing possible during on-line processing as well by performing checking of a flag and exchanging of signals between a file access processing part and file restoration processing part. CONSTITUTION:In a file access processing part 2, whether the flag C is up or not is examined during file restoration processing. If the flag C is down, the part 2 erects the flag A during file accessing and starts file access processing. When the file C has been up, the part 2 erects the flag D during the queue for file access processing, and does not start the file access processing. When the file restoration processing end signal 5 from a file restoration processing part 3 arrives, the flag A is erected in the same manner as with the part 2 and the access processing is started. |
