Title: File collection method in remote maintenance system
Inventor: OGASAWARA SHIGERU
IPC: H04Q9/00
Filed: 1988-02-29
Abstract: PURPOSE:To reduce a file collection time and to decrease capacity of a magnetic disk on the remote maintenance system by collecting only a difference in an exchange file in the remote maintenance system. CONSTITUTION:Every time data is written in a file memory 16 from a central processing unit 10, address information and data sent from a file memory data processor 14 are stored by one day's share and the result is preserved as a preceding data difference file LAFA. The difference information is added to the difference file LAFA at the end of the date similarly in the succeeding day to revise the preceding data difference file LAFA. Then a guarantee file REF is sent to an external storage device (EX.MT) once per week and the date difference file LAFB is copied to the preceding data difference file LAFA at that time to revise the guarantee file and the preceding date difference file. Thus, the collection time of the exchange file is reduced and the file capacity of the magnetic disk is reduced.
