This menu function allows you to save and restore either the complete database contents and log contents, or only the modifications made since the last database or log backup. The medium used for the backup can be a tape, a file, or a pipe. The save or restore operations only apply to the addressed server database (serverdb). Ad-hoc backups are performed interactively; i.e., CONTROL expects that the required parameters are entered in screens. Input can also be expected for started backups, e.g., if the capacity of the backup medium is not sufficient for the backup. Incorrect entries or a timeout occurring due to delayed input can have the effect that the backup is aborted.
