This bug did not make the OSP 8.0 release.  It is being deferred to OSP 10.

I think the BZ is possible once the RGW patch (0) is merged.

puppet-tripleo (1) and puppet-cinder (2) supports configuring Ceph backups to use swift.

2: https://github.com/openstack/puppet-cinder/blob/master/manifests/backup/swift.pp

We can enable cinder-backup in OSPd10 deploying with:

  -e environments/cinder-backup.yaml

it defaults to the swift backend, we need to test if by deploying rgw as a drop-in replacement for swift, cinder-backup works as expected.

With the merging of (1), this should be ready for testing in the next puddle. 

1) https://review.openstack.org/#/c/289027/

I have used the upstream bits and have verified Cinder backup working working with Ceph RGW providing object storage services.

This should be verified and (if successful) closed when the next stable puddle is available.
