The "Scheduling" tab of the "New archive" window allows backup scripts to be executed automatically at a certain time or times.
All settings on this page are ignored if "Save script as" is selected on the "Options" tab.

• Create archive immediately - the archive will be created immediately when the "Enter" key is pressed or the "OK" button is selected, unless the "Save script as" option has been selected, in which case the script will be written and the user will be asked if it should be executed.
  
  Note: If a differential backup is being created, using a reference archive which has been encrypted, this option will be the only one available.
  

• Schedule script - the script will be executed at the specified time on the selected date, once only or at the intervals selected. This function uses the Windows Task Scheduler. To reschedule a scheduled backup or access other features of the scheduler, select Edit->Schedule Manager from the main menu.
  
  Note: On Windows XP this option is disabled. DarGUI cannot schedule a backup on Windows XP or earlier versions of Windows.
