Re: Openstack Backup and Restore

As far as we understand from what you explained, when I make an instance backup, only the snapshot taken at that time is assigned as the root device and we cannot change it. Because this is not available in nova specs. If I understand correctly, we already have another obstacle ahead of us. In the metadata, the rbd url of the disk is located in the direct_url field of the snapshot/image/volume in Rados GW. Openstack does not allow changing this field. It gives 403. So, in this case, does this mean that we have to create a new instance from scratch for the instance to which we will connect the volume backup?
