The name of the service is DreamObjects. No affiliation to Dreamhost but doing something as basic as storing files as a service hardly deserves to be called a clone.
It's not just storing files as a service in some generic way. It's storing objects using exactly S3's API (or at least a subset) so e.g. programs and libraries written to use S3 can use DreamObjects instead by just changing the base URL. That's a clone of S3 as much as Linux was a clone of UNIX, and as much of a clone as there can be when the original is closed source.
Disclaimer: I'm on the GlusterFS team at Red Hat, which puts me pretty close to the Ceph team but not actually one of them. I've never had anything to do with Dreamhost.
