Current situation:
Upload Policies are mandatory. Therefore no matter what upload time you define, you'll have backups for all machines in any case.
Feature request:
Ability to create a "No Backup" or "No Upload" Policy.
Use Case:
For example if you have kiosk machines or teaching class rooms that just need to have an image and some app layers, you don't really care about backups. Once you're finished with a training or if a machine brakes, then you just re-provision the Base-Layer.
