# NAS 概览

NAS 功能可在 VergeOS 系统内提供文件级存储/访问，使您能够创建文件卷以存储在分布式存储中，并挂载外部文件系统。

## NAS 功能的优势

* 在您的 VergeOS 系统内管理并备份文件级存储
* 利用 VergeOS 的存储效率优势（如重复数据删除）来实现文件级存储
* 挂载外部文件系统，以便在您的 VergeOS 环境中访问
* 将数据导入您的 VergeOS 系统，用于接纳外部工作负载、执行备份等。
* 从 VergeOS 导出数据和/或工作负载，用于第三方备份、合规等。

## NAS 设置步骤

1. [**添加 NAS 服务**](/run-the-platform/zh/nas/nas-service.md)
2. **可选** - [**与 Active Directory 集成**](/run-the-platform/zh/nas/nas-join-ad-domain.md)
3. **创建卷** (每个卷都是一个独立的目录树，可针对安全性、快照、访问、杀毒、最大大小和共享设置进行自定义。)
   * [**本地卷**](/run-the-platform/zh/nas/nas-local-volumes.md) 存储在 VergeOS 内部，占用 vSAN 存储。
   * [**远程卷**](/run-the-platform/zh/nas/nas-remote-volumes.md) 是挂载到 VergeOS 系统并显示为本地的外部文件系统。
4. [**创建共享**](/run-the-platform/zh/nas/nas-shares.md) 以向 NAS 卷提供 NFS 和/或 CIFS 访问。
5. **可选** - [**配置卷快照**](/run-the-platform/zh/nas/volume-snapshots-restores.md) 用于自定义卷保留和/或静默快照（非静默的 NAS 卷可从系统快照中恢复，用于还原。）

## 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.verge.io/run-the-platform/zh/nas/overview.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.
