I'm trying to take system backup on Windows 8.1 Pro (EFI system partition + C:\ drive). It works perfectly well via Control panel however such command in command prompt fails:

wbadmin start backup -backupTarget:F: -allCritical -vssFull -quiet
wbadmin 1.0 - Backup command-line tool

Retrieving volume information...
This will back up (EFI System Partition),BOOTCAMP(C:) to F:.
The Windows Backup engine could not be contacted. Retry the operation.
The remote procedure call failed.

Some errors in error log (sorry it's in Polish):

  • I would suggest: 1, Create the directory: C:\dumps. 2. Download Procdump.exe from Sysinternals/Microsoft and save procdump.exe to C:\dumps. 3. In an admin prompt run CD \dumps, followed by procdump -i -ma C:\dumps. Reproduce the issue and then make the first dump file if it creates 2 available. You can then run procdump -u . – HelpingHand Jul 22 at 20:59
  • I got the dump. Now what? – Marek Zakrzewski Jul 22 at 21:09
  • Could you make it available? Other option is you download the Windows SDK, and install the Debugging Tools for Windows. From there, you can open WinDbg, configure Symbols and choose to load the dump file. Then the analyis begins. !analyze -v is the absolute minimum output. You could share that if you go down this route. – HelpingHand Jul 22 at 21:12
  • This could be it: windowsforum.com/threads/… I got UEFI install and my recovery partition is 300 MB – Marek Zakrzewski Jul 22 at 21:28

I just typed this command and all works back!

wbadmin delete catalog
