Quizplus · Accepted Answer

In a direct access file system, files are typically backed up immediately before an update run to ensure that a recent and accurate copy of the data is available in case of system failure or errors during processing. The grandfather-father-son approach is a common method for organizing backups, but it is not specific to direct access file systems. Processing a transaction file against a master file does not necessarily create a backup file, and if the master file is destroyed, it may be possible to reconstruct it from backups or other sources. Therefore, choice C is the best answer.
