I want to create a backup account that will only backup data on a few servers. This backup account will run a scheduled task to backup the current system state. I have the account made but the account does not have enough permissions. I want to apply the least privileges principle but the only account who can perform this job is the Domain Admins. We do not have a power user group or other integrated windows group.
What would be the best method for applying my backup account backup only enough permissions to run the backup system state in a scheduled task?
