# FAQ

## What are the current limitations of Network File Storage?

Network File Storage has its own set of limitations. For more information, see [<mark style="color:blue;">Technical Specifications and Limitations</mark>](/cloud/backup-and-storage/network-file-storage/overview/tech-specification-limitation.md).

## What are the benefits of the NFSv4.2 protocol compared to NFSv3?

Currently, <code class="expression">space.vars.ionos\_cloud</code> supports **NFSv4.2**, which is the latest version of the NFS protocol for Network File Storage. It allows standard Linux users to read and write directly to storage, scaling performance linearly for both IOPS and throughput, maximizing the limits of storage, and network infrastructures. Some of its benefits are as follows:

* Reduced protocol overhead with compound operations and caching.
* Efficient file operations with minimal server interaction.
* Enhanced performance with multiple parallel network connections.
* Live data movement without interruption.
* Detailed file-level access and performance telemetry.

## 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.ionos.com/cloud/backup-and-storage/network-file-storage/faqs.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.
