Actions:

  New Table Name (clone): This action will create a new table by cloning the snapshot content. There are no copies of data involved. And writing on the newly created table will not influence the snapshot data.
 
    Restore a specified snapshot. The restore will replace the content of the original table, bringing back the content to the snapshot state. The table must be disabled.
