Group Policy - Backup Account Delegation

I am trying to backup group policies using the System account from a domain controller.

Note that I cannot use a real user due to compliance requirements. They prevent me from saving the password under the scheduled task. And this is why I opted for using the System account.

The problem is it only backs up about 20 of the 200 or so policies that I have in my environment. I can find no difference in the rights on the ones that backup and the ones that do not.

So my question is where should I be checking the rights on the group polices? The only place I can find to check is under the delegation tab (Which is already providing System with edit/delete/mod)
