Why backup Windows Server 2019 to NAS?

Windows Server enables a computer to manage network roles (print server, domain controller, web server, file server) and provide services for other networked computers. It’s used in business settings under most conditions and involves a lot of important data & information.

NAS (Network Attached Storage), also popular with companies, enables multiple clients to store and share files with fast data access and easy administration. If you are considering backing up Windows Server like 2019, NAS could be an ideal destination for the following advantages:

• It offers you a considerable storage space to back up Windows Server, and costs lower in the long term.
• Data stored in NAS could be accessed and shared with multiple clients on the network.
• With NAS, it’s able to stream media like movies, TV shows, music, and photos on multiple computers.
• Compared with PC, NAS storage is less likely to be damaged by accidents.
• Some NAS drives have RAID options to duplicate data on multiple drives as NAS disaster recovery strategy.

4 Methods for Windows Server backup to NAS

Since there are so many benefits to backing up Windows Server to NAS, how to achieve it? Here I compiled 4 methods and hopefully one of them could suit your case.

☛ Method 1. Windows Server Backup

Windows Server Backup is the built-in backup solution for Windows Server, including the latest system Windows Server 2019 and 2022. It did not have the ability to back up to the network in the early days, and only since 2012 has it added “Remote shared folder” option.

But there are still some functional limitations of Windows Server Backup, like the latter backup will overwrite the former one, so it can only keep one full backup. And even with the remote backup feature, there are many users reported errors when specifying NAS drives as destination.

To perform Windows Server backup to NAS successfully, it's recommended to create a VHD or iSCSI Target on your NAS drive beforehand, then select the created volume as the backup destination in Windows Server Backup.

The steps are honestly quite complicated. You could refer to following tutorials with detailed screenshots.

>> Create a virtual hard disk and attach it to NAS

>> Create an iSCSI Target on NAS device

Then you can create the backup task in Windows Server Backup, and select the NAS as select an additional drive.

>> Backup individual folders on Windows Server
