iTunes always reset the "Automatically Back Up" option to "This Computer" So, this section of iTunes idevice option always keeps resetting to "This Computer" from "iCloud", whenever the sync finishes / the device is reconnected.



Is there any guess why this is happening, even though iCloud Backup is turned on in my idevice's settings? Any solution I can try to do?
Solved - it seems that this error happens when you restore your idevice from icloud backup.

Go to idevice's settings>iCloud>Backup and disable and reenable iCloud Backup, and iTunes will now remember this settings.

tl;dr: it didn't have something to do with iTunes, the idevice was the problem.
