Google Photos' unlimited cloud backup is one of the best things Google's done with an app product in a while, if you ask me. Unlimited storage of intelligently compressed (or original quality for some phones) photos and videos means you can keep every moment your smartphone (or other camera) captures without ever [realistically] worrying about storage space. It's great. But other photo backup services do exist, and some people just don't like to use (or trust) the cloud for backing up their personal data.

So, do you use Google Photos cloud backup feature? If not, why not?
