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.
