Within Cinder, volume snapshots provide a way to non-disruptively copy a volume. This allows for volume backups. It also enables more advanced backup features and provides the ability to boot an instance from a given snapshot or point in time.
In this section, we will show you how to create a snapshot, refresh a snapshot, and delete a given snapshot.
Ensure that you are logged in to the Ubuntu host where the Cinder command-line utilities are installed and source your OpenStack environment admin credentials.
