Can OpenStack live backup instances (Pike)?
Hi,
We're running Pike. I'm trying to implement backups - incremental, non incremental, snapshots, anything. At the moment we can't work out if it is at all possible to live backup instances, i.e without interruption to normal functionality? Or is Ceph / other storage required for CoW?
We've tried both with volume backed instances (cinder nfs), and local storaged backed instances with the following:
openstack server backup create
openstack volume backup create
In both cases, the instance is taken offline for 20 minutes to backup.
Thanks,
Elliot
