Basically, I have 4 years worth of photos. I currently have 12GB worth of photos and videos. I want to back them up onto iCloud and have them there for historical purposes (kinda like how we keep old family albums in the closet) but I don't want them on my iPhone 6. I want to have my iPhone 6 empty so that I can start a new collection of pictures and videos. Is there any way to do this?
