Will iCloud Photo Library be backed up in iTunes Backup?
I sync and do backups of my iPhone 4s only to my PC/ through iTunes. Recently, my phone as automatically turned on the "iCloud Photo Library" in order to "optimize iPhone storage". Though I currently do not have a problem with this, I am getting a new iPhone soon so I am worried my photos will not be included in my iTunes backup (since it is part of iCloud) to transfer to my new phone.
Also, if I try to turn iCloud Photo Library off, it says "This iPhone was not able to download 796 full resolution photos and videos. If you continue, the low resolution versions of the photos and videos will be removed." What does this mean? If I continue to turn it off, will my photos be deleted?
HELP!
