Cinder backup/restore over AZ is possible by storing object storage like following.

How can I backup/restore(or move) Cinder volume(which is stored in object storage by cinder-backup command) OVER REGION?

This is sample of backup/restore over AZ.

Cinder AZ

# cinder availability-zone-list
+-------+-----------+
|  Name |   Status  |
+-------+-----------+
|  nova | available |
| nova2 | available |
+-------+-----------+

In AZ1(nova), Cinder backup to object storage

# cinder backup-create --display-name <display name> <volume name>
# cinder backup-list

In AZ2(nova2), Create new volume

# cinder create --display-name <new volume name> --availability-zone nova2 1

In AZ2(nova2), Restore

# cinder backup-restore --volume-id <new volume uuid> <backup volume uuid>

Thank you.

There actually and easier way to migrate volumes between AZs using cinder migrate.

http://docs.openstack.org/admin-guide...

As far as migration between regions you can use your back and restore commands .

Backup volume in region 1 and then restore to region 2.

sfcloudman, Thanks for the reply.

Sorry my question title was wrong. correct title is backup/restore, not migrate.

I've tried before about cinder migration to different cinder backend. but the status was wrong and I could not delete the volume having vague status. This is other issue, just information.

Regarding backup/restore over Region, As I described, I could confirm to backup/restore over AZ. Actually the cinder data is stored in ceph storage.

My point of question is Is "cinder-restore command" able to access to cinder backup data of ceph storage in different Region?

Thank you.

The only real way that I know is if your ceph cluster spans regions or you use cinder back up to swift and your swift cluster replicates to both regions.

In nova, it's possible over Region like this. - glance image-download from region1 - glance image-create to region2 I'm looking for same way as nova for cinder.

Anyway I'll try to check about connection between ceph and cinder over region. Thanks.
