# Backup and restore

We recommend using your database’s tools to back up your SonarQube 9.9 data.

{% hint style="info" %}
**For AI agents:** You're in the SonarQube Server 9.9 documentation. For a list of all 9.9 pages, see the [SonarQube Server 9.9 page index](https://152261287-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FBmptmznn7RpPe5u7vdup%2Fuploads%2F7O6jgZAiehDGe0FMXDaC%2Fsonarqube-server-9.9-llms.txt?alt=media). For the whole site, see the [page index](https://docs.sonarsource.com/llms.txt) or the [full text](https://docs.sonarsource.com/llms-full.txt). For another version, replace 9.9 in the URL with that version. The [latest version](https://docs.sonarsource.com/sonarqube-server/) has no version number in its URL.

### Backing up data <a href="#backing-up-data" id="backing-up-data"></a>

Most databases come with backup tools. We recommend using these tools to back up your data.

### Restoring data <a href="#restoring-data" id="restoring-data"></a>

To restore data from the backup and or trigger a full ElasticSearch reindex, follow these steps:

1. Stop the server.
2. Restore the backup.
3. Drop the Elasticsearch indexes by deleting the contents of `<SONARQUBE_HOME>/data/es7` directory.
4. Restart the server.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.sonarsource.com/sonarqube-server/9.9/instance-administration/backup-and-restore.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
