Explanation:
Scheduled Backup
Although you cannot use Backup And Restore to schedule System Image backups, you can use the Wbadmin command-line utility to perform this function. For example, to initiate a System Image backup of the C: drive to the H: drive, you run the following command from an elevated command prompt:
wbadmin start backup backuptarget:h: -include:c: -quiet
As with any command-line routine, you can put this command into a batch file and schedule it by using Windows Task Scheduler. You need to configure the task to run with administrative privileges. You do this by specifying an administrative user account and selecting the Run With Highest Privileges check box on the General tab of the tasks Properties dialog box

Task Scheduler
With Scheduled Tasks, you can schedule any script, program, or document to run at a time that is most convenient for you. Scheduled Tasks starts every time that you start Windows and runs in the background, and it starts each task that you schedule at the time that you specify when you create the task.
