NTBackup offers the ability to schedule backup jobs. When you use NTBackup and take the "schedule" option, NTBackup builds a command-line string and then uses the Windows "Scheduled Tasks" functionality to schedule it to run.
You can adjust the schedule manually once you have initially created it, from the control panel.
Click: Start -> Control Panel -> Scheduled Tasks, Double click on the job and then adjust the settings....
When you create a scheduled backup job in Windows 2003, a selection script (.bks) file is created with a list of folders and files that are to be backed up and that are to be excluded from the backup job. You can edit this list of files by clicking Load Selections on the Job menu in the Backup tool.
When you click the Load Selections command, load the .bks file that is named for the backup job that you created. Any files, folders, or network shares that you scheduled for backing up are selected. You can make any appropriate changes, and then click Save Selections on the Job menu to save them.
Ntbackup.exe saves the .bks file with the list of files to be backed up under your profile in the Drive:Documents and SettingsUsernameLocal SettingsApplication DataMicrosoftWindows NTNTbackupData folder. The file is named with the name of the backup job.
