I think it should be photo back up option available when you are starting your back through iCloud because When i start to make any kind of back with iCloud that time this option always available. iCloud automatically backs it up daily over Wi-Fi when your device is connected to a power source. Once you plug it in, everything is backed up quickly and efficiently. That’s because Backup is like everything else in iCloud: convenient and completely effortless.
