# WebDAV Backup

Cherry Studio data backup supports backup via WebDAV. You can choose an appropriate WebDAV service for cloud backup.

Based on WebDAV, you can use `Computer A` $$\xrightarrow{\text{备份}}$$ `WebDAV` $$\xrightarrow{\text{恢复}}$$ `Computer B` to achieve multi-device data synchronization.

#### Taking Nutstore as an example

1. Log in to Nutstore, click the username in the top right corner, and select “Account Information”:

2. Select “Security Options” and click “Add App”

7. On the same page, click \[Back up to WebDAV] or \[Restore from WebDAV], and you can also set the automatic backup interval and maximum number of backups.

{% hint style="success" %}
The easiest WebDAV services to use are generally cloud drives:

* [Nutstore](https://www.jianguoyun.com/)
* [123pan](https://www.123pan.com/)(membership required)
* [Aliyun Drive](https://www.alipan.com/)(purchase required)
* [Box](https://www.box.com/) (Free storage is 10GB, and the maximum file size is limited to 250MB.)
* [Dropbox](https://www.dropbox.com/) (Dropbox offers 2GB for free, and you can invite friends to expand it to 16GB.)
* [TeraCloud](https://teracloud.jp/en/) (Free storage is 10GB, and you can get an extra 5GB by inviting others.)
* [Yandex Disk](https://disk.yandex.com/) (Free users are provided with 10GB of storage.)

Next are some services that require self-hosting:

* [Alist](https://alist.nn.ci/zh/)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.cherryai.com.cn/docs/en-us/pre-basic/settings/data-settings/webdav.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.
