Norton Ghost 14 - Backing up on system start up

Hello,

 

I would like Norton Ghost 14 to back up everytime the machine is switched on. My machine is configured to start without the need to log on. Ghost does not appear to have an option to backup on system startup. I have tried the backup option when a user logs on, but this does not work when your machine is configured to startup automatically. 

 

Can any one help?

 

Thanks.
