Are "Cinder Backup" possible to use with NetApp NFS Driver?

An error occurs when I use Cinder Backup with NetApp NFS Driver.

Is this similar to Bug 1247743.

cinder failed to create a backup with NFS driver

And may I understand that it occurs in all NFS not only NetApp NFS Driver?

Hello

Yes this is a known bug and a fix has been submitted to the cinder project for bug 1247743.
