Cinder supports alternative snapshot methods: backups (compressed and stored in swift), glance image (also stored in swift).
These snapshot methods may save costs in public OpenStack cloud providers.
Describe the solution you'd like
Add extra snapshot methods support into config and process the snapshots accordingly.
