How Do I Query the Snapshot Information of a CSS Cluster?

You can query snapshot information only if cluster snapshots are enabled and some snapshots have been created.

You can check them on the CSS management console or query them by running commands on Kibana or OpenSearch Dashboards.

Querying Snapshots on the CSS Management Console

Log in to the CSS management console.
In the navigation pane on the left, expand Clusters. Select a cluster type based on the target cluster. The cluster list is displayed.
In the cluster list, click the name of the target cluster. The cluster information page is displayed.
Click the Cluster Snapshots tab.
In the cluster snapshot task list, click the target snapshot name, and check snapshot information in the displayed dialog box.

Querying Snapshots by Running Commands

Log in to the CSS management console.
In the navigation pane on the left, expand Clusters. Select a cluster type based on the target cluster. The cluster list is displayed.
For an Elasticsearch cluster, click Kibana in the Operation column to log in to Kibana. For an OpenSearch cluster, click Dashboards in the Operation column to log in to OpenSearch Dashboards.
Expand the menu in the upper-left corner, and choose Dev Tools.

Run the following command to query the snapshot repository information, that is, the basic cluster snapshot settings.

GET _snapshot/_all

Example response:

{
  "repo_auto": {
    "type": "obs",
    "settings": {
      "bucket": "123xxx",  	// OBS bucket name
      "chunk_size": "2g",  	// Chunk size in snapshots (unit: GB)
      "endpoint": "obs.xxx.example.com:443",  	// OBS VPC endpoint
      "max_restore_bytes_per_sec": "0MB",  	// Maximum recovery rate (per second)
      "compress": "true",  	// Whether to enable data compression
      "base_path": "css_repository/css-xxx",  	// Backup path
      "region": "xxx",  	// Region
      "max_snapshot_bytes_per_sec": "40MB"  	// Maximum backup rate (per second)
    }
  }
}

Run the following command to query the snapshot list:

GET _snapshot/repo_auto/_all

Example output (two snapshots are returned):

{
  "snapshots": [
    {
      "snapshot": "snapshot-2dc3",  	 // Snapshot name
      "uuid": "VW5y2NBJS9iPh7YcGLxxxx",  // Snapshot ID
      "version_id": xxxxxxx,  		// Internal cluster version
      "version": "x.x.x",  		// Cluster version

        ".opendistro_security"
      ],
      "data_streams": [ ],  		// Data streams

      "end_time": "2025-08-30T01:41:57.469Z",  	// Snapshot end time
      "end_time_in_millis": 1756518117469,  	// Snapshot end time in milliseconds
      "duration_in_millis": 401,  			// Snapshot creation duration (from start to completion) in milliseconds
      "failures": [ ],  				// Failed shards during snapshot creation
      "shards": {  					// Shard statistics
        "total": 1,  					// Total number of shards
        "failed": 0,  					// Number of failed shards
        "successful": 1  				// Number of successful shards
      }
    },
    {
      "snapshot": "snapshot-dd37",
      "uuid": "FD4VcooLS8yjPY3w0-x-xx",
      "version_id": xxxxxxx,
      "version": "x.x.x",
      "indices": [
        ".kibana",
        ".opendistro_security"
      ],
      "data_streams": [ ],
      "include_global_state": true,
      "state": "SUCCESS",
      "start_time": "2025-08-30T01:54:55.750Z",
      "start_time_in_millis": 1756518895750,
      "end_time": "2025-08-30T01:54:55.950Z",
      "end_time_in_millis": 1756518895950,
      "duration_in_millis": 200,
      "failures": [ ],
      "shards": {
        "total": 2,
        "failed": 0,
        "successful": 2
      }
    }
  ]
}

To query information about a specified snapshot, run the following command:

GET _snapshot/repo_auto/{snapshot_name}

Replace snapshot_name with the actual snapshot name. Wildcard matching is supported.

(Optional) Run the following command to delete a specified snapshot:
```
DELETE _snapshot/repo_auto/{snapshot_name}
```
Exercise caution when choosing snapshots to delete.
