# 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”
3. Enter the app name and generate a random password;
4. Copy and record the password;
5. Obtain the server address, account, and password;
6. In Cherry Studio \[Settings] → \[Data], fill in the WebDAV information;
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.

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/)
* [Cloudreve](https://cloudreve.org/)
* [sharelist](https://github.com/reruin/sharelist)

# Agent Instructions

## 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.cherryai.com.cn/docs/en-us/pre-basic/settings/data-settings/webdav.md?ask=&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.
