Ghost/Backup Solution needed

Does anyone know of any third party utilities that will enable me to AUTOMATE Ghost backups? I currently Ghost several PC’s as a means of backups….I know there are other solutions to doing this, but I am looking for all FREE type backup solutions. Supervisor is currently a little to “cheap” to buy into any extra backup utils at this time of the year.

I am looking for something Automated, that can work with Ghost, and if Not, at least Automated to create full or partial hard drive images through automation on its own. These backups would be scheduled to run in the evenings after everyone has gone home.

Thanks for all your support.
