How to connect to WebDAV with Cloud Backup Sync?

WebDAV

Web Distributed Authoring and Versioning (WebDAV) is an extension of the Hypertext Transfer Protocol (HTTP) that facilitates collaboration between users in editing and managing documents and files stored on web servers. WebDAV is one of the most popular protocols used for accessing files over the Internet, because of its HTTP-based design. For more information about WebDAV, please visit http://www.webdav.org/.

WebDAV is supported by commercial and open-source web server software. Many online storage providers also offer WebDAV accessibility in addition to their proprietary protocols. QNAP offers the Cloud Backup Sync App for accessing WebDAV-compatible cloud storage. Because there are many online storage services that provide free space, you can use the App to back up your data to multiple cloud storage services in order to take advantage of as much free space as possible. There are also cloud services that work as a protocol translator and allow you to use WebDAV to access a variety of cloud storage services so that you can access all of your cloud storage from one place.

You can create an account and storage space first, then you can use the storage space to create backup and restore jobs.

Account

After opening Hybrid Backup Sync, expand the “Storage Space” tab on the left panel and click “Profile” to create a new cloud account. In this page, you can create, edit, and delete accounts and configure the rate limit settings for each account. If you modify the cloud storage account identity (like changing its username or access key) the state of the corresponding jobs will be reset and all of the files will need to be uploaded again as the backup destination has also changed.

To create a cloud account, click “Create” and select “Cloud Account”.

Choose a cloud service and click “Next” button to enter the account information.


The Cloud Backup Sync App allows you to use WebDAV to access various cloud storage services. Although WebDAV is a standard protocol, cloud storage service providers may offer different authentication parameters. Please consult your service providers for more information.

Storage Space

After creating a cloud account, go to “Storage Space” to create a cloud storage space. Then you can use this storage space to create backup and restore jobs.

Click the “Adding Storage Space” icon, choose “On cloud”, click a cloud service, then enter a storage name and select a cloud account to set a storage space.


You must select a folder or use a new folder for storage space. If the file names of your backup data contain special characters, you need to enable the name encoding option such that your data can be properly stored in the cloud storage. When you restore the data, the original file names will be restored by the Cloud Backup Sync App.

If you have not created a cloud account, select “New Profile” and click “Settings” to create a new account.
