If you are just looking to store, not share, Drop Box is a cloud storage site to consider. Choosing a backup method also depends on what device you take most of your photos with. If you use your phone a lot, either the manufacturer or the service provider should have a cloud backup system for your specific device or account. You could just buy a 2 to 4 TB USB backup drive to maintain control of them yourself. Burning them to DVD from a backup drive is easy then. You can store them in a fireproof box then to protect your treasures from computer crashes, remote server loss, hacking, the Russians, or any other unforseen event. You really should have some kind of hard copy or redundant series of backup drives if you really really really want protection from loss.
