Open Stack

Hello all!

I'm currently using openstack queens with cinder 12.0.10.
I would like to a backend I'm using a NFS-share.

Now i would like to spit my backups up to two nfs-shares.
I have seen that the cinder.volume.driver can handle multiple nfs shares.
But it seems that cinder.backup.driver can not.

Is there a way to use two nfs shares for backups?
Or is it maybe possible with a later release of Cinder?

regards,
MaSch
