Currently there isn't a lot you can do with Snapshots in Cinder. You can create them. You can clone a volume from them. You can delete them.
The proposal is to make Snapshots first class Cinder objects by:
- defining a "snapshot replicate" method which can replicate a snapshot to another storage backend with the same type of Volume Driver.
* Optionally allowing the Volume Driver to direct storage-backend to storage-backend transfer of snapshots.
- Allowing a snapshot to be dependent on a prior snapshot of the same volume stored on the same backend.
- Allowing Volumes to be dependent on the snapshot they were cloned from.
- Allowing time consuming operations involved in creating/replicating a snapshot to be tracked in the Snapshot status.
