Hi Wodel,

Currently configuring multiple cinder backup backends is not supported.
This was brought up in our last cinder meeting on 06 April, 2023[1].
A spec was proposed to implement this[2] but there aren't any patches to implement this.
Christian Rohmann (crohmann on IRC) has shown interest in this topic, so probably you can contact him about the details and can collaborate on the effort.

Hi,

Could cinder-backup be configured with multiple-backends, ceph and nfs for example?

Regards.
