docs: <p>
  Copies the specified automated cluster snapshot to a new manual cluster snapshot. The source must be an automated
  snapshot and it must be in the available state.
  </p>
  <p>
  When you delete a cluster, Amazon Redshift deletes any automated snapshots of the cluster. Also, when the
  retention period of the snapshot expires, Amazon Redshift automatically deletes it. If you want to keep an
  automated snapshot for a longer period, you can make a manual copy of the snapshot. Manual snapshots are retained
  until you delete them.
