Description RHOS Integration 2013-12-12 16:37:33 UTC
Cloned from launchpad blueprint https://blueprints.launchpad.net/cinder/+spec/cinder-backup-volume-metadata-support.

Description:

Creating this blueprint to cover the work required for https://bugs.launchpad.net/cinder/+bug/1137908 which will require modifications to all existing ceph backup drivers (Ceph, Swift and TSM).

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.
