Comment 3 Yogev Rabl 2013-11-04 11:35:27 UTC 
The command was: cinder backup-create <volume-id>
Comment 4 Eric Harney 2013-11-13 20:19:41 UTC 
Backups are not supported for the NFS or GlusterFS volume drivers in 4.0.  (Hence NotImplementedError.)
Comment 6 Flavio Percoco 2014-03-17 11:01:10 UTC 
This seems to be fixed upstream for both NFS and GlusterFS. Looks like ready to be packaged.
