我们正在尝试使用以下命令恢复以前创建的快照：

POST /_snapshot/my_backup/my_snapshot_2023.06.30/_restore

字符串
但是，该命令不断收到错误消息... index [.xxxxxx] because an open index with same name already exists in the cluster. ...。索引名称.xxxxxx表示内部系统索引。

{
  "error": {
    "root_cause": [
      {
        "type": "snapshot_restore_exception",
        "reason": "[my_backup:my_snapshot_2023.06.30/Pl0QeAojSgq1p6PYI_JdDg] cannot restore index [.ds-ilm-history-5-2023.02.17-000001] because an open index with same name already exists in the cluster.

      }
    ],

此外，我们试图通过this post后面的命令DELETE /_all删除所有索引，但它也不起作用。错误消息为：

{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "Wildcard expressions or all indices are not allowed"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "Wildcard expressions or all indices are not allowed"
  },
  "status": 400
}

测试中的Elasticsearch示例运行在本地虚拟机上，我们有虚拟机的备份。所以，我们可以尝试任何命令，如果有必要，没有风险。

我们的问题：

命令GET /_cat/indices不显示任何内部索引。那么，如何列出所有的内部系统指标呢？
我们是新的备份和恢复功能，所以我们想知道是否有什么错误时，采取的快照之前。我们使用了PUT /_snapshot/my_backup/%3Cmy_snapshot_%7Bnow%2Fd%7D%3E命令，不确定是否应该包含额外的参数来忽略系统索引。
是否可以删除所有索引，包括内部和外部？

我们将非常感谢任何提示和建议。

- You can use below command to delete index or data stream. #Delete an index DELETE my-index #Delete a data stream DELETE _data_stream/logs-my_app-default - You can use below command to restore the specific index. POST _snapshot/my_repository/my_snapshot_2099.05.06/_restore { "indices": "my-index,logs-my_app-default" }

- Restore to rename index (new index) first using below command: POST _snapshot/my_repository/my_snapshot_2099.05.06/_restore { "indices": "my-index,logs-my_app-default", "rename_pattern": "(.+)", "rename_replacement": "restored-$1" } - Delete the original Index and reindex data from rename index to original index # Delete the original index DELETE my-index # Reindex the restored index to rename it POST _reindex { "source": { "index": "restored-my-index" }, "dest": { "index": "my-index" } }

请在下面找到我对每个问题的答案。你没有提到你正在使用哪个版本，因此下面的答案是基于最新的ElasticSearch版本。
您可以使用以下命令列出所有索引：
GET _cat/indices/_all？expand_wildcards=all
如果您想恢复特定索引，则有两个选项可以恢复它。

第一个选项，删除现有的特定索引并恢复。

字符串

第二个选项，恢复重命名索引，重新索引到原索引

您可以使用以下命令删除所有索引和数据斯特雷姆：

# delete all index
DELETE *?expand_wildcards=all

# delete all data stream
DELETE _data_stream/*?expand_wildcards=all
