Hello. I feel that people don't use cinder-backup because it is slow and not show more stats such as how many percent to complete a backup job, Nguyen Huu Khoi On Wed, Apr 12, 2023 at 2:06 PM Christian Rohmann < christian.rohmann@inovex.de> wrote:

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.

I am just as interested as you to have this feature. First to allow transitioning from one backup backend to another, but also to offer multiple "types" of backups. One could i.e. be "onsite" the other "offsite".
I gladly rework the spec and propose it for Bobcat. But I do not have the capacity to implement this. Yes, cinder itself and the already present support for different volume types could serve as some kind of blueprint, but having more than one type of backup storage likely is a little more complicated to implement and transition to as it first appears.
So what are your thoughts on the matter then?
