Backing up VHDs with the Windows File System plug-in

Use the Windows File System plug-in to back up attached or detached VHDs in the following environments:

• Stand-alone server, all operating system versions
• Windows Server cluster

You must attach the VHD file in a Windows Server 2019, 2016, or 2012 for SOFS or SMB cluster to back up the VHD file with the Windows File System plug-in.

If the VHD file is attached as a volume and you want to include the VHD in the backup, then select the Back up Natively Attached Virtual Hard Disks checkbox in the Backup Command Line Options dialog box when you set the options for the backup.

To exclude an attached VHD file from the backup of a volume, clear the Back up Natively Attached Virtual Hard Disks checkbox.

The Windows File System plug-in backs up the detached VHD file as a file in the file system with a .vhd file name extension. You must select the volume on which the VHD file is located for the backup.
