I have users that are running local backups to USB drives. The computers are Windows 7. Windows Backup and Restore is not very flexible with backup sets. There is no way (that I have found) to have Windows automatically free up space on the backup target. The users need to manually clear space. The problem is that Backup and Restore is protected by UAC. The users can't open the program, much less get to the point where they can delete older backups.
Is there a way to enable users to get in to backup and restore without disabling UAC? If not, is there a way to have Windows automatically free up space on the backup target?
I've tried some basic GPOs with no luck.
