Computer backup system operable with open files

Abstract

A backup program for a computer system with a hard disk maintains a record of changes made to the data in a file being backed up. During backup both the original and update file portions or records are stored, and the backup program reads the original data while other applications read the updated data. It is ensured that the file is in a 'good' state by delaying the start of the backup operation for a predetermined period.
