KCS Backup always fails to execute a backup task on a Windows Server 2012 R2

Issue

• I installed KCS Backup on a fresh Windows 2012 R2 machine, but when I create a new Backup task, it will always fail.
• The Trace file C:\TCOSS\Trace\KCSBackupSrv.log file shows following trace output:

2014-09-15 13:49:59,859 DEBUG [Thread=Worker] [KCSBackupSrv] Init complete
2014-09-15 13:49:59,939 ERROR [Thread=Worker] [KCSBackupSrv] KCSObjectsBackupMgr.ctor:Object reference not set to an instance of an object.

• Increasing the tracelevel in C:\TOPCALL\KCSBackup\KCSBackupSrv.log4net.config to e.g. DEBUG does not give any more information.
• What is the reason for this problem and can it be solved somehow?

Cause

The problem is caused by a known bug

Bug 564003:

KCSBackup: NullPointerException while retrieving Win32_Registry WMI class

Solution

You can use the following workaround to solve the problem:

• Copy the attached WMIReadValues.vbs and WMICorrectValues.vbs to any local folder on the machine where KCSBackup is installed
• Login with a local Administrator user
• Right-click the start button and select the menu option Command Prompt (Admin)
• Within this command prompt window nagivate with the cd command to the folder, where the these two vbs files are located Within this command prompt window execute the command: cscript WMIReadValues.vbs
• Check the values reported after MaximumSize and ProposedSize. If MaximumSize is empty and ProposedSize is 0 as shown below, it is most likely the reason for the problem with KCSBackup.
  Microsoft (R) Windows Script Host Version 5.8
  Copyright (C) Microsoft Corporation. All rights reserved.
  Caption: Registry
  CurrentSize: 102
  MaximumSize:
  ProposedSize: 0
  Status: OK
• In this case execute the following command: cscript WMICorrectValues.vbs
• Both values "MaximumSize" and "ProposedSize" should now show a value of 2048 as shown below:
  Microsoft (R) Windows Script Host Version 5.8
  Copyright (C) Microsoft Corporation. All rights reserved.
  Caption: Registry
  CurrentSize: 109
  MaximumSize: 2048
  ProposedSize: 2048
  Status: OK

Afterwards it is recommended to reboot the whole machine and check then to create a backup task with KCSBackup.
