Apple creates an iCloud backup from the business area on a device with user enrollment! Because it’s user enrollment, we can’t turn it off, right? Is there any documentation on what’s in the backup?
User Enrollment and Shared iPad depend on a company using Apple Business Manager and Managed Apple IDs/iCloud services. These are separate from consumer iCloud services. With that said, the options you have to manage what devices/users can use these services and what options are enabled are managed in Apple Business Manager.
But how do you restore an iCloud backup?
