Challenge

Windows File Level Restore hangs on "Starting restore session" for abnormally long period of time while free disk space on drive C:\ keeps decreasing dramatically on the machine where the Veeam Backup & Replication Console is launched.


You may that find the following location of the cache file constantly growing:

C:\Windows\system32\config\systemprofile\AppData\Local\mount_cache{GUID}

or

C:\Windows\SysWOW64\config\systemprofile\AppData\Local\mount_cache{GUID}.
 

Cause

The issue occurs when guest Windows has Transactional NTFS (TxF) turned on. When mounting to Veeam server it can cause NTFS driver to enter infinite loop trying to re-apply transaction log.

Solution

To resolve:

  1. Login to the guest OS of the machine being backed up as administrator.
  2. Open an Administrative Command Prompt
  3. Execute 2 following commands for each logical disk in VM.
    Example for disk C:
    • fsutil resource setautoreset true C:\
    • fsutil resource setavailable C:\
  4. Run the backup job to create a new restore point.
    Note: This will correct the issue for all future restore points, and is not retroactive.
  5. Test the Windows File Level Restore again
