The Symptom

When trying to create a backup that contains a volume beyond 2088958 Megabytes (2TB) with Windows Server Backup in Windows Server 2008 or 2008 R2, you may receive an error message saying "Volumes larger than 2088958 megabytes cannot be protected.".

The Cause

Windows Server Backup creates a virtual hard disk (VHD) file for each volume included in the backup. A VHD file is easy to mount and restore, but it has a 2TB limit in size. Therefore, volumes larger than 2TB cannot be protected.

The Solution

Microsoft has realized this problem, so VHDX file that supports maximum of 64TB was introduced in Windows Server 2012. To fix this problem, you can upgrade your Windows Server to Server 2012 or newer version. If you do not want an upgrade, there is also a workaround for Windows Server 2008R2, which is to make a partial volume backup instead of full volume backup.

Open Windows Server Backup, and click on “Backup Once” or “Backup Schedule” to set up a backup job.

Backup Once

2. Follow the wizard to configure the backup, and in the Select Backup Configuration screen, select Custom instead of Full server.


3. Add all the items on the volume that is large than 2TB.

Select Items

4. Then specify where to save the backup.

Select Backup Destination

5. In the confirmation screen, click “Backup” to start the backup process.


You can also create files and folders backup with Wbadmin from command line. However, in Windows Server 2008, you can only include full volumes in the backup with Windows Server Backup. In that case, you can use third party software to lift the Windows Server Backup limitations.
