Solution

On Windows Server 2003 and 2008, the Backup Exec Shadow Copy Components file system implements a Volume Shadow Copy Service (VSS) Requester to protect critical operating system and application service data, and third party application and user data via VSS Application Writers. A VSS Application Writer is specific code within an application that participates in the Volume Shadow Copy Service framework to provide point-in-time, recovery-consistent operating system and application data. When a data protection operation of Shadow Copy Components is performed, the status of the involved VSS Application Writers must be queried to determine its status during the backup or restore. (Problem occurs when activity on a volume is preventing all volumes from being snapped.)

During a Shadow Copy Components data protection operation, if a VSS Application Writer involved in the operation reports a failed status, then the data protection operation will fail. 
 
If you encounter this error in conjunction with an error on Exchange circular logging please see 000004881
 
To troubleshoot this error, please perform the following steps immediately after a failed Shadow Copy Components backup has been identified:

  1. Open a Command Prompt on the server that is pointed on the Job Log with failure (Run with elevated permissions if its Windows 2008).
  2. Type the following command: VSSADMIN LIST WRITERS (Figure 1)
    Figure 1 - VSSADMIN sample output: No Errors
     

    Figure 2 - VSSADMIN sample output: Errors Detected.
      
  3. Review the output and identify the Last Error failure status for the specific VSS Application Writer that was involved in the data protection operation (Figure 2, failed "NTDS" VSS Writer). Ensure that the writers are all showing a State of " [1] Stable " and that Last Error is showing " No error ."  If Last Error states:
    • Retryable Error, then retrying the data protection backup operation might resolve the VSS Application Writer's initial failure.
    • Non-Retryable Error, view the Event Viewer's Application Log for information regarding the cause and possible solution to this issue.
  4. If the VSS Application Writer failure does not reset after a period of time, Backup Exec for Windows Servers continues to fail, or the native backup utility fails, reboot the system and contact the specific company that produced the VSS Application Writer for further assistance.
    • Note: In most cases rebooting the server has resolved such issues. In case the issue is unresolved and the Writer continues to show failed status, please refer to the Microsoft Article mention below.
  5. If the issue further persists one can try to update the VSS package through "https://support.microsoft.com/default.aspx?kbid=833167" but if Service Pack 1 for windows 2003 is already installed then it will supplement this answer ID.
  6. If this issue appears on a Windows Servers 2003 with SP1 already installed, a Microsoft hotfix KB903234 which is mentioned in Microsoft KB913648 will be helpful in fixing this issue.
  7. How the update will help in fixing the issue?
    The update that is described in this article(KB 903234) is designed to optimize the way that the Shadow Copy Client accesses snapshots. Without this update installed, the Shadow Copy Client opens every existing shadow copy for a particular volume. After you install this update, the Shadow Copy Client searches for unique versions of a shadow copy before the Shadow Copy Client opens the shadow copy. This new behavior significantly reduces the load that the Shadow Copy Client puts on the server.

    • Note:
      • For Windows server 2003/2003R2:
      • For Windows server 2008/2008R2:
        • Issue with querying the writer and errors found are resolved with  2008 servers by Microsoft, hence rebooting the server would normally resolve the writer issue.
  10. The following error can occur if C: drive on the server does not have enough free space.
    • Snapshot provider error (0xE000FED1): A failure occurred querying the Writer status. Check the Windows Event Viewer for details. Writer Name: Event Logs, Writer ID: {EEE8C692-67ED-4250-8D86-390603070D00}, Last error: The VSS Writer failed. The operation cannot be retried (0x800423f4), State: Failed during prepare snapshot operation (8).
    • To fix such issues, free up some space on the C: drive and retry backups.
