* <p>
* When you make periodic snapshots of a volume, the snapshots are
* incremental, and only the blocks on the device that have changed since
* your last snapshot are saved in the new snapshot. When you delete a
* snapshot, only the data not needed for any other snapshot is removed.
* So regardless of which prior snapshots have been deleted, all active
* snapshots will have access to all the information needed to restore
* the volume.

* <p>
* You cannot delete a snapshot of the root device of an Amazon EBS
* volume used by a registered AMI. You must first de-register the AMI
* before you can delete the snapshot.
* </p>
