Bug Description
Problem:
When backups are created with backend / driver being ceph, there
currently is no way to enable the image feature, 'fast-diff'.
Fast-diff adds another property to the object map, which makes it
much faster to generate diffs between snapshots of an image, and the
actual data usage of a snapshot much faster.
Features applied to backup images unfortunately do not depend on the regular cinder settings,
each feature is handled explicitly by a config option. Following this approach support for
EXCLUSIVE_LOCK and JOURNALING was implemented with https:/
I created a patch with the proposed changes: https:/

Thank you michael-mcaleer for picking this up.
