Snapshot not saving my multisite backup to Dropbox.

I have installed Snapshots and have it set to perform a weekly full backup to my Dropbox account. In All Sanpshots, it shows one backup completed back in Dec. 2013 and no others. When I look in my Dropbox there is nothing, not even the Apps/WPMU DEV Snapshot/ folder that is says it will create. It looks like it's saving a weekly copy in my wp-content/uploads/snapshot folder instead. I also have it set to backup the database daily and I can't find those backups in Dropbox OR in the site folders. Please help.
