I have a Macbook Air. I love it, but the hard drive is too small to fit my entire photo library. At this point the hard-drive is full and I need to find a way to move the files to a back-up location. I know I could just buy an external hard drive and move the files manually, but I would rather find a way where I could automate the process of backing up and moving older photos (or better yet, photos not recently viewed) to an external hard-drive and a remote backup location. I know of a few services that will automatically back up the photos (if I remember to leave the app running) but they don't remove the files, and I have no way of knowing which files have successfully been backed up and/or could be restored if I wanted to. So I don't feel like I have enough confidence in my backups to feel like I can delete the files to clear up space.
So I'm wondering if you know of a way to automate this process.
