The following has worked for me to enable file level VCB backups of windows 2008 R2. (TRY AT YOUR OWN RISK - MAKE SURE YOU UNDERSTAND WHAT YOU ARE DOING HERE)
1. Open a command prompt
2. type "diskpart" and hit enter, then enter the commands below
select vol c
shrink desired=100
list vol (verify that volume C is still selected)
Create Part Primary
List vol (verify that the new 100mb volume is selected)
Format fs=ntfs quick
Assign letter r
Select vol 1 (1 is typically the existing boot partition – verify this first)
Inactive
Select vol r
Active
3. in a new command prompt, run the following:
bcdboot c:\Windows /s r:
4. Go back to the diskpart window, and run:
Remove letter=r
5. Exit all command prompts
6. Reboot and delete the old boot partition
7. Reboot to verify.
