  creation. By default, when `ignore_unavailable` option is not set and an index is missing the snapshot request will fail.
  By setting `include_global_state` to false it's possible to prevent the cluster global state to be stored as part of
  the snapshot. By default, entire snapshot will fail if one or more indices participating in the snapshot don't have
  all primary shards available. This behaviour can be changed by setting `partial` to `true`.

  === Stopping currently running snapshot and restore operations
  
  The snapshot and restore framework allows running only one snapshot or one restore operation at a time. If a currently
  running snapshot was executed by mistake, or takes unusually long, it can be terminated using the snapshot delete operation.
  The snapshot delete operation checks if the deleted snapshot is currently running and if it does, the delete operation stops
  that snapshot before deleting the snapshot data from the repository.
  
  The restore operation uses the standard shard recovery mechanism. Therefore, any currently running restore operation can
  be canceled by deleting indices that are being restored. Please note that data for all deleted indices will be removed
