Rebooted with 0.9.7 and there is a problem with the dos_restore.cmd file.
IF EXIST K:\WINDOWS\System32\Config\sam set WindowsDrive=K:
IF EXIST J:\WINDOWS\System32\Config\sam set WindowsDrive=J:
IF EXIST I:\WINDOWS\System32\Config\sam set WindowsDrive=I:
IF EXIST H:\WINDOWS\System32\Config\sam set WindowsDrive=H:
IF EXIST G:\WINDOWS\System32\Config\sam set WindowsDrive=G:
IF EXIST F:\WINDOWS\System32\Config\sam set WindowsDrive=F:
IF EXIST E:\WINDOWS\System32\Config\sam set WindowsDrive=E:
IF EXIST D:\WINDOWS\System32\Config\sam set WindowsDrive=D:
IF EXIST C:\WINDOWS\System32\Config\sam set WindowsDrive=C:
I have Win 7 on C: and Win 8 Customer Preview on I. I guess this will work as it will see the one on C: last and set the WindowsDrive variable correctly, but I think a better method would be for you to look at the HOMEDRIVE environment variable then set WindowsDrive to that value when building the batch file. Should always work.
Ran a manual backup and it worked. Checked C:\Windows\temp and not I have two sets of vss files:
C:\Windows\Temp>dir vss*
Volume in drive C is D370_C
Volume Serial Number is C89E-70E8
Directory of C:\Windows\Temp

05/24/2012 09:23 PM 296 vss_start553.bat
That works but will end up leaving more and more vss* files there over time. You need to figure out why you were not replacing the vss files before then go back to just the single instance of each.
Were you deleting them before writing new ones previously or just trying to write over them?
