Disclaimer: I think this project is silly in the face of tools like rclone + borg.
Hammer2's wikipedia article lists dragonfly bsd as it's solely supported os and ceph requires one to... Manage a ceph cluster.
Now the question of whether this is similar to those technologies becomes easy to answer: no, they aren't similar. This tool aggregates external storage providers while the tools you reference require you to be your own provider.
My personal recommendation (if this project interests you) is to check out initiatives like upspin.io and Tahoe lafs
