The default value for the [snapshot](https://www.elastic.co/elastic/docs-builder/docs/3028/reference/elasticsearch/curator/snapshot) action is `True`.
<tip>
  During snapshot initialization, information about all previous snapshots is loaded into the memory, which means that in large repositories it may take several seconds (or even minutes) for this command to return even if the `wait_for_completion` setting is set to `False`.
