summary: " 版本： 7.6-7.13
 简而言之，当 Elasticsearch 由于各种原因无法从快照恢复索引时，就会出现此错误，例如索引已存在、权限不足或快照损坏。要解决此问题，您可以在恢复前删除现有索引，确保 Elasticsearch 集群具有访问快照存储库所需的必要权限，或者检查快照的完整性并在其损坏时重新创建。
日志上下文 #  日志 “cannot restore index [” 的类名是 RestoreService.java。我们从 Elasticsearch 源代码中提取了以下内容，为那些寻求深入上下文的人提供参考：
request.indexSettings(); request.ignoreIndexSettings()); try { snapshotIndexMetadata = indexMetadataVerifier.verifyIndexMetadata(snapshotIndexMetadata; minIndexCompatibilityVersion); } catch (Exception ex) { throw new SnapshotRestoreException(snapshot; "cannot restore index [" + index + "] because it cannot be upgraded"; ex); } // Check that the index is closed or doesn't exist  IndexMetadata currentIndexMetadata = currentState.metadata().index(renamedIndexName); IntSet ignoreShards = new IntHashSet(); "

日志 "cannot restore index [" 的类名是 [RestoreService.java](https://www.geeksforgeeks.org/java-lang-class-class-java-set-1/)。我们从 Elasticsearch 源代码中提取了以下内容，为那些寻求深入上下文的人提供参考：

```java
request.indexSettings(); request.ignoreIndexSettings());
 try {
 snapshotIndexMetadata = indexMetadataVerifier.verifyIndexMetadata(snapshotIndexMetadata;
 minIndexCompatibilityVersion);
 } catch (Exception ex) {
 throw new SnapshotRestoreException(snapshot; "cannot restore index [" + index +
 "] because it cannot be upgraded"; ex);
 }
 // Check that the index is closed or doesn't exist
 IndexMetadata currentIndexMetadata = currentState.metadata().index(renamedIndexName);
 IntSet ignoreShards = new IntHashSet();
