Hi Grady,

Thanks for reaching out to us!

To block the user from backing up files to the iCloud account, navigate to Policies -> iOS -> Restrictions -> Allow iCloud Settings -> Uncheck ‘Backup’.

This would be supported for iOS 5.0+ and supervised iOS 13.0+ devices.

In addition to this, to prevent the users from syncing the documents on the device with their iCloud account, you can uncheck the option ‘Sync documents’.

Check out the link to know more on all the restrictions that can be pushed from the Hexnode portal to the enrolled devices: https://www.hexnode.com/mobile-device-management/help/set-up-ios-mdm-restrictions-using-hexnode-mdm/
