Description RHOS Integration 2013-12-12 18:33:14 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/cinder/+spec/cinder-live-backup.

Description:

Cinder currently supports backing up a volume only if the volume is 'available' i.e. not attached or busy. This blueprint proposes to add support for taking a backup of a volume that is attached to an instance (in-use) in a similar way to creating a snapshot of a live volume with --force.

This would involve silently taking a snaphot of the live volume, and backing up from that snapshot thus hopefully eliminating data corruption issues from data changing during the backup process.

We will also need to make sure that the following bug gets sorted for Glance/boot metadata in order to allow restore of bootable volumes:
