iCloud backup and Photos on iCloud
Hi! It's my first Iphone so a lot of things are new to me. My question concerns using iCloud in an optimal way. I paid for 50GB extra on iCloud to have all my photos there. They are still transfering (14% from yesterday) but I recognized that there is also Backup which takes up 16GB and it's mainly "Library of photos". Please find screenshots attached.
So my question is: are these photos duplicated? Is there any point in having Photos on iCloud if they are already in Backup?
