Hi,

Currently the cinder-backup service has two deployment options: tightly
coupled, and non-coupled.

The non-coupled version is the usual way to deploy it, as you can run it
in Active-Active mode, and it only supports a single backend.

The coupled deployment allows you to have multiple backends, one backend
per cinder-backup service and host, but each backup backend can only
backup volumes from the cinder-volume service deployed on the same host.

Cheers,
Gorka.
