I performed an Itunes backup of my Ipad Pro to my local PC and the resulting backup size (1.8Gb) is way smaller than the Ipad Storage used as shown in the Ipad/Settings/Ipad Storage (49.6Gb). I tried again restarting the Ipad and PC from fresh without success, the backup size is always 1.8Gb. For the record, I don't use iCloud, I have it disabled completely in Settings, and for backing it up, I have the iPad connected to the PC directly with a USB C cable. Also iPadOS version is latest 15.5 and same with iTunes (latest version). Thanks for any hints.
