Is my iPhone backing up photos to iTunes in error?
Hello
I'm looking for some clarification with my iPhone back-ups as I think my iTunes back-ups are including photos, when Apple Support states that photos are not included in an iTunes back-up if iCloud Photo Library is being used (About backups for iOS devices - Apple Support). I have around 40gb of photos, which are synced to my iCloud Photo Library and are also on my iPhone SE (128gb).
I noticed that my Application Support/Mobile Sync folder was large (50gb), so deleted my iPhone back-up in iTunes, reducing that folder to around 3gb. When I backed up again, the folder increased back up (to 40gb), and my available hard drive space reduced by 40gb.
The usage breakdown of my iPhone (according to iTunes) is as follows:
Documents & data = 9.9gb
Apps = 5.59gb
Photos = 33.42gb
Other/book/audio = 0.5gb
If iTunes were not backing up my photos, as per Apple Support's page referenced above, I would have expected my Mobile Sync folder to be around 16gb based on the numbers above. Any ideas why it's so much larger and what else can be making the folder so large? Apple doesn't give the option to omit photos from an iTunes back-up, which is what the iCloud Photo Library is supposed to provide instead.
Thanks in advance for any advice.
