Dropbox and Google have put a lot of effort into making photo backups an integral feature of their respective services. Now Eye-Fi is launching a service that backs up all of the photos you take with your smartphone and your camera. Launching today, Eye-Fi Cloud offers unlimited photo uploads for $49 per year, regardless of resolution or file size. The pricing compares favorably to Google and Dropboxs offerings, especially if you take a lot of photos, but Eye-Fis service is designed to only work with pictures, not any file you care to back up.
