Being new to Elasticsearch I'm trying to determine how to encrypt backups (i.e. snapshots). The snapshot and restore web page says nothing about encryption so I'm assuming it's not a feature of the system but would be a post backup step that would need to be done before the data is written to long-term storage. Is that right?
