You can’t Use WSB to Backup Server to QNAP NAS.

Due to an SMB issue, Windows Server Backup may fail when you try to backup to QNAP NAS network location. Many users have received an error saying "The specified backup disk cannot be found" during the backup process. In this situation, you have two useful methods:

Method 1:  Create Windows Server backup to QNAP NAS with VHD or VHD file.

To make it, you need to create a VHD or VHDX (Windows Server 2012 or later version) file using on the QNAP NAS location using Disk Management. After creating, you will see a new drive on your server computer and you can backup your server to the virtual disk the same as to a local drive.

Method 2: Backup to QNAP NAS in Windows Server with a third-party tool. 

By using this method, you don't need to create a VHD or VHDX file first. And you just need to add the network path of QNAP NAS as backup destination during the backup configuration process. The entire process is in simple 3 steps.

Honestly, the second way will be much easier. I prefer to use it. Anyway, I'll show you both ways to backup Windows Server 2012/2016/2019/2022 to QNAP NAS below.

Method 1: Backup Server to QNAP NAS with VHD or VHDX File

Here you will learn the first way to backup server to QNAP NAS with VHD or VHDX file. The process is divided into two parts, you need to create a VHD or VHDX file first with Computer Management, then backup server to this file using Windows Server Backup. For detailed steps, please continue to see below.

Step 1. Open Server Manager and click Tools > Computer Management > Disk Management, then you will be navigated to a new window.

Step 2. In the Disk Management window, go to the Actions tab, click More Actions and then Create VHD.

Create VHD

Step 3. Then, you will see the Create and Attach Virtual Hard Disk window, click Browse and select the shared folder on the QNAP NAS. Specify a file name for it and click Save. 

Select Network Share on QNAP Server

Step 4. Specify the virtual hard disk format (VHD or VHDX) and disk size, click OK to confirm.

Specify VHD and Disk Size

Step 5. Right-click the VHD or VHDX and then select Initialize Disk > MBR or GPT partition style and click OK.

Initialize Disk

Step 6. Right-click the unallocated space and select New Simple Volume. Then, follow the on-screen instructions to finish the reset of steps.

Step 7. Open Windows Server Backup and create a backup task with the newly created VHD or VHDX disk. 

Tip✍: If you are not familiar with Windows Server Backup, please refers to this guide and remember to select VHD or VHDX disk as backup destination: create system image backup in Windows Server 2016.

Method 2: Backup Windows Server to QNAP NAS with Third-party Tool (Easier)
