Intune, shared ipad, quota

[KK20]

I use intune as an MDM for shared ipads. Enrolled in ASM, assigned to intune as MDM, enrollment into intune as shared ipad with a couple of configuration profiles and app installation profiles. All seems to work well.

 

I have one user who takes a lot of pictures and video and they have seemingly run out of space on the ipad. The ipads are 32Gb and there is 13gb free on the ipad but the user is told there isnt enough space. I cannot find anywhere in intune to set a quota or remove one. Worryingly, if I click on the device in intune, I can see the user and there is a line that says "has data to sync = yes" "data quota = 0" "data used =0" . if I click on a pupil ipad and look at a pupil user I get "has data to sync = no" "data quota = 6,278,144 KiB" "data used = 999,836 KiB". The ipads all use the same configuration and enrolment profiles. These two ipads have only ever had a single user log onto them so there arent multiple users clogging up the ipads (and in any case there is plenty of space on them)

 

I cant find any information on what this is, where to set it etc. Ideas?

Well this just gets worse. Deleted all the videos (around 200Mb worth) , all seemed well for a few hours. Then it filled up again without any new photos being taken! Worse still, once this happens it is really hard to copy photos with the cable, onedrive client freezes etc. Delete a couple of pictures and you can get going again. As you can see from the screenshot, 15Gb free...

syncing solved. I added a configuration profile that stopped icloud sync (noone used it, noone even logged into icloud). The storage was sorted.

 

https://learn.microsoft.com/en-us/mem/intune/enrollment/device-enrollment-shared-ipad

"A Shared iPad consists of a pre-defined number of user partitions. User partitions ensure that each user’s apps, data, and preferences are stored separately on the iPad. If you allow it, these partitions can be backed up to iCloud for seamless transition across other shared iPads in your organization."

 

Seems that the free space is carved up whether you use it or not. This carved up partition is then carved up again for apps, photos, documents etc. It also seemed to allocation a block for icloud sync too - hence why a user was full. I cannot seem to find anywhere on the ipad or intune to say how much space each user is taking up. Since the most we ever have is three profiles I have dropped the enrollment profile to 4. That should sort it.
