Exit Code -4 Failure



A System State backup fails to back up successfully and presents the following error message:


WBAdmin process failed with exit code -4, arguments: start systemstatebackup -backupTarget:<X:> -quiet


This error will most likely occur each time you try to run the backup.




The cause of this problem stems from the present of non-NTFS volumes included in the System State source.  If files which need to be included in the System State are present on non-NTFS volumes, they cannot be shadow copied and cannot be backed up.  To fix this issue, the non-NTFS partition must be identified and converted to NTFS in order for Windows Server Backup to proceed with the backup generation process.

To identify which volume is the non-NTFS one, do the following:

  1. Open the Disk Management Utility by pressing the Windows+R keys or "Start" and then "Run" to open the Run dialog.
  2. Type diskmgmt.msc and hit the "Enter" key.
  3. Once the Disk Management window opens, locate the drive without a file system label of NTFS.


To convert the non-NTFS volume to NTFS, use the procedure from this article.  The command is as follows:

convert x: /fs:ntfs

...where  x: is the volume you want to convert.  Please note that although the process is nondestructive, working with hard drive formatting always contains some risk of data loss.  Make sure you have a backup of data stored on the non-NTFS partition prior to converting the drive.


If following this procedure does not fix the problem, refer to System State Troubleshooting.
