An old printed photo is precious often because it’s the only copy that exists. In the digital age, that type of scarcity isn’t a problem. You can easily make copies of a photo or have inexpensive prints made. And yet, digital photos suffer from a different type of scarcity: one hard drive failure can wipe out your photos — all of your photos — in an instant. The solution is to ensure you have a solid backup system in place. You also want to make sure you can view your photos in the distant future. Unfortunately, as I discuss at the end of this chapter, that isn’t an easy guarantee given how software and hardware will change over the years.
