<h1 class="topictitle1">Querying the Automatic Snapshot Creation Policy</h1>
<div id="body1708331107508"><div class="section"><h4 class="sectiontitle">Function</h4><p>CSS allows you to use snapshots to back up and restore Elasticsearch cluster data. By storing a snapshot in an OBS bucket, you save a point-in-time copy of the cluster's data. By restoring this snapshot, you can restore the cluster to a previous state. There are two ways to create snapshots to back up a CSS cluster: automatic and manual. This API is used to query the automatic snapshot creation policy.</p>
<ul><li><p>Automatic snapshot creation: Snapshots are automatically created daily or weekly based on a preset time schedule, ensuring ongoing data protection. By configuring an automatic snapshot policy, you reduce manual operations while improving backup reliability and efficiency.</p>
</li><li><p>Manual snapshot creation: You create snapshots manually for special occasions, for example, prior to a high-risk operation (such as a cluster upgrade). This ensures you can restore data using snapshots in case anything should go wrong. Manual snapshots provide additional flexibility.</p>
</li></ul>
