# Automatically activate Snapshot

**Enable Snapshot service to use Server Disaster Recovery**

To use the Server Disaster Recovery (SDR) service effectively, users need to enable the Snapshot service in the Regions where the primary and backup servers are located. Snapshot is an important feature that allows creating quick backups of data on disk, helping to ensure data recovery in case of an incident.

**Auto-Activate:**

If you have not enabled the Snapshot service, SDR will automatically enable it for you to ensure you have full access to the DR service features. This simplifies the installation and configuration process, while ensuring the continuity and security of your data.

**Note:**

* Activating the Snapshot service may incur additional costs. Please refer to GreenNode's pricing table for more details.
* You can check the activation status of the Snapshot service in the Volume management section on GreenNode Console.

**Summary:**

* To use SDR, you need to enable the Snapshot service in the relevant Regions.
* If not activated, SDR will automatically activate this service for you.
* Please check activation status and associated costs before use.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.vngcloud.vn/vng-cloud-document/backup-center/disaster-recovery-center-drc/server-disaster-recovery-sdr/sdr-management/automatically-activate-snapshot.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
