Challenge

When attempting to perform a Windows FLR (Guest Files ‘Windows’) the restore fails with:



No disks have been mounted. Either disks of this type aren’t supported or some errors occurred. See log file for details.

Solution

• FAT
• FAT32
• NTFS
• ReFS*

Troubleshooting Steps
──────────────────────────────────────────────────────────

1.  Clear all temporary files from “C:\Users\\AppData\Local\Temp\”

Note: When the Veeam Backup Service account is ‘local system’, the temporary directory used is C:\Windows\Temp.

2.  Open an Administrator Command Prompt and run the following commands:

(The the installation path for Veeam if it was upgraded from 6.5 is: C:\Program Files\Veeam\Backup and Replication\)

cd “C:\Program Files\Veeam\Backup and Replication\Backup”
vdk remove
vdk install

3.  Confirm that the account being used for the Veeam Backup Service has the "Perform volume maintenance tasks" right assigned to it. This can be located within the group policy (gpedit.msc) under:

Computer Configuration>Windows Settings>Security Settings>Local Policies>User Rights Assignment

4.  Reboot the Veeam server
