Backing up from the cml fails with the msg "The filename, directory name, or volume label syntax incorrect."
I have two local drive C and D. I'm trying to backup to Drive D.
Syntax: wbadmin start systemstatebackup -backuptarget:D:
Using this link for the syntax - wbadmin start systemstatebackup

I've found a solution. You have to modify these registry settings.
hkey_local_machine\system\controlset001\services\vsock
hkey_local_machine\system\controlset002\services\vsock
hkey_local_machine\system\controlset\services\vsock

Original setting is \SystemRoot\system32\DRIVERS\vsock.sys
Change them to %SystemRoot%\system32\DRIVERS\vsock.sys
Restart the server.

I've added %SYSTEMROOT%\System32\Drivers to the path and restarted. The systemstatebackup still fails with the same msg.
I have to change the registry keys for the systemstatebackup to succeed.

My questions are why do I have to change the registry keys for the backup to succeed?
Is my syntax incorrect?
What am I missing or doing wrong?


Note:
I can backup the systemstatedata to Drive D using the GUI.
I can backup the C Drive to the D Drive from the command line. wbadmin start backup -backuptarget:D: -include:C:
I have the user account in the local admin group.
I'm running CMD elevated with admin privileges.
