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. There is a workaround to create Windows Server backup to QNAP NAS. You can create a VHD or VHDX (Windows Server 2012 or later version) file on the QNAP NAS location as a local drive using Disk Management. Then you can create a backup to the virtual disk which is actually saved on the QNAP NAS. However, if you do not like this workaround, you can use third party software to backup to QNAP NAS.

Backup software that works well with QNAP NAS

Professional NAS backup software, AOMEI Backupper perfectly supports QNAP NAS, so you will not have a scratch while backing up to NAS network location. Based what you want to include in a backup, it provides System Backup, Disk Backup, Partition Backup, and File Backup. You can create scheduled/automatic backup over NAS network location, and incremental backup and differential backup are both supported. When you have saved a lot of backup versions, you can merge them into one backup or enable Backup Scheme to automatically delete previous backups. What’s more, it also allows you to start many computers within LAN in order to perform a system restore using AOMEI PXE tool.
