Description Gregory Charot 2020-12-07 13:46:54 UTC 
Description of problem:

As a user i want to easily restore a removed backuped by cinder backup to a different AZ than the original volume.

Version-Release number of selected component (if applicable):

Steps to Reproduce:

3.

Actual results:


Expected results:


Additional info:

Currently possible with the cinder create command
$ BACKUP_ID=$(openstack volume backup list --name vol-dcn1 -f value -c ID)
& OS_VOLUME_API_VERSION=3.51 cinder create --availability-zone az-dcn2 --name vol-dcn2 --backup-id $BACKUP_ID 1


Goal is to integrate this with cinder backup tooling or API.
Comment 1 Alan Bishop 2021-03-04 18:12:25 UTC 
The patch merged on master, and is on target for OSP-17.
Comment 2 Gregory Charot 2021-04-13 18:23:54 UTC 
not a GA must have, moving to 17.0.2
Comment 10 Alan Bishop 2023-08-07 14:35:07 UTC 
Doc updates for this BZ will be limited to updating the command to restore a backup (step 2) in [1].

[1] https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/17.1-beta/html-single/deploying_a_distributed_compute_node_dcn_architecture/index#proc_backup-and-restore-across-edge-sites_appendix

However, it turns out cross-az backups themselves are broken in OSP-17 (bug #2229750), which makes it difficult to verify the new command for restoring a cross-az backup. I'm clearing the needinfo now, and will revisit the doc issue when the blocking bug is cleared.

According to our records, this should be resolved by python-cinderclient-7.4.1-1.20220727131518.4f72e6f.el9ost.  This build is available now.
