Now that Amazon is offering unlimited free storage for photos (to Prime accounts), I started using their Cloud Drive to automatically backup my photos. However, it backups up my videos too and I only have 5 GB of storage for non-photos. I'd like to backup videos to Dropbox or OneDrive where I have 10 and 15GB of storage respectively. Unfortunately, both the Carousel and Amazon app upload everything without giving me a choice. Is there a way to tell these apps to only backup photos or video, but not both?
