4. Reboot the Veeam serverMore information
To restore files from a VM running Microsoft Windows ReFS 3.x, the console and mount server must be installed on machines running Microsoft Windows Server 2016.
To support restore of files from a VM running Microsoft Windows ReFS 2.0 or earlier the console and mount server must be installed on machines running Server 2012/Server 2012 R2.
If the server you are attempting to restore from has volumes with native 2012 data deduplication, the Veeam console and mount server must be installed on the same operating system and also have the “Data Deduplication” role enabled. The “Data Deduplication” role appears under "File and ISCSi Services" in server manager.
If the Windows FLR continues to fail after attempting the steps outlined in this KB, please attempt and Other-OS FLR. For more information regarding how to do that please review the following:
