I'm trying to understand how cloud storage affects local storage. Can you guys help? When I say...upload several photos to google drive app (using iphone 5), the goole drive app local usage increases effectively NOT freeing up local storage. Doesn't that defeat the purpose of cloud storage from a mobile device? I ultimately wanted to upload several photos to a "cloud", to free up space on the phone so I can update to ios7, but its moving space from one place to another. Make sense? Help.
