This is a cautionary tale. iCloud is not reliable storage. You must backup all your photos and documents to your own machine. Do not rely on iCloud.
When my iPhone upgraded to iOS 11.4 three years of photos and all my documents vanished, on the phone and on iCloud. I spent an hour with tech support trying to resolve the issue, which was kicked up to Apple's engineers. In the end, Apple said my files were just gone and there was nothing they could do about it.
It is inconceivable to me that iCloud lost my files. But that's what happened.
Tech support at an Apple store had told me that iCloud was a valid and reliable backup for my phone and that I didn't need to backup to my computer. (My iphone was having problems and unable to back up to any computer.) Not only was I given bad advice by Apple staff, I've lost irreplaceable pictures of my children.
Don't let it happen to you.
