Add volume metadata support to Cinder backup
Creating this blueprint to cover the work required for https:/
A bit more info:
Following dicussions with the cinder team there are mixed opinions about how best to do this. To resolve this lets be clear on the objective. When we backup a volume in cinder we want to be able to revover that volume even if the database and/or cinder cluster go offline, perhaps by restoring to a new cloud. In order to facilitate this it would be necessary to backup all required metadata to rebuild an equivalent volume.
What is proposed here is to have a versioned interface that each backup driver can call to retrieve a 'complete' set of metadata required to reconstruct a volume following total loss of the original metadata.

Whiteboard
avishay: So we need an import_backup API as well, if there our database got wiped out and we want to import an existing backup.
@avishay: yes indeed, that has been dicussed too i.e. what do we do if we lose our cloud and want to restore from our backups - import tool/api. That will require a blueprint of its own.
