In addition to rclone... you could run a VPS that has the various services as fuse mounts and otherwise sync between them in CRON ... however, probably best to only actually use one of them in practical terms.
It depends on what you want to do, but can probably be accomplished in a <= $5 VPS.

I am looking for something that can backup Dropbox, Google Drive and Amazon Cloud to a 3rd party service. What do people recommend?

Thanks but appears Amazon stopped issuing api keys for Amazon Drive so stuck, at least for a fully automated solution.
