I've been doing some looking around the web and haven't found a good way to manage files being stored online. I've tried Mozy and have heard of Amazon S3, but none of them allow me to go back and forth with my files. Essentially I want something LIKE dropbox, but much cheaper. Is there anything out there that is similar? I want to be able to back up and download 100 - 200 GB of storage if possible. Anything would help, thanks!
