0x80042306: The shadow copy provider had an error. Please see the system and application event logs for more information  

Description

This error occurs when a VSS provider blocks the creation of the VSS snapshot. This may be caused by:

  •   Installing a new 3rd party VSS provider.
  •   An existing provider becoming corrupted.
  •   Destination drive not being compatible with NTFS format. 


To check this problem, run NTBackup and try performing a manual backup of your System State. If it is a VSS problem, the backup will fail. 

If NTbackup is successful, check your scheduling to make sure that the backup does not clash with other system activity. Otherwise, follow the instructions given below.

Solution

  • VSS Providers 
    Check to see if there are any non-standard providers that are causing the problem when creating a VSS snapshot. To do this, go to the command prompt and execute the following command:

    vssadmin list providers

    If there are any non-standard providers listed, consider uninstalling them. Note that the Microsoft default providers are generally very reliable, so uninstalling 3rd party providers may solve the problem.
    If the "vssadmin list providers" command hangs, it is likely that a newly installed VSS provider is malfunctioning. In this case, uninstall these products to resolve the issue.
  • Multiple Backups
    Ensure that the backup is not running at the same time as another backup, as the custom provider may only allow one snap-shot at a time.
  • Corrupted data on the drive to be backed up
    Run the CHKDSK command on each drive with the /f switch to fix any errors on the disk.
  • VSS believes the system is in setup process 
    Check the status of the system by following these steps: 

    a. Go to the Registry Editor and locate HKEY_LOCAL_MACHINE\SYSTEM\Setup 
    b. Ensure that the following registry values are set to 0: 
    SystemSetupInProgress 
    UpgradeInProgress
  • VSS dll`s are corrupted 
    Re-install the VSS dll`s by following these steps: 
    a. Using command prompt, CD to the WINDOWS\system32 directory.
    b. Stop the Volume Shadow Copy service by executing the command "net stop vss".
    c. Register the DLLs (click here).
  • COM+ needs to be re-installed
    Re-install COM+ by following these steps: 
    a. Backup and then delete HKLM\Software\Microsoft\COM3.
    b. Boot to Recovery console and rename clbcatq.dll to ~clbcatq.dll. Make sure to use the tilde (“~”) character. 
    c. Boot the machine to normal mode and in Control Panel, open the Add or Remove Programs tool and then open the Add/Remove Windows Components tool. Do not Make any changes, just click Next. This reinstalls COM+.
  • Destination drive is not formatted for NTFS

0x80042308: The specified object was not found  

Description

This error indicates that the backup process is having difficulties with backing up Open Files.

Cause

This is due to a problem with the VSS  when performing backups of any open files or files that are in use at the time of the backup.

Solution

According to Microsoft Premier Support this is the correct procedure to follow when re-registering the Volume Shadow Copy service DLL's.

1. Change directory to System32 
c:\>cd c:\Windows\System32 
c:\Windows\System32>Net stop vss 
c:\Windows\System32>Net stop swprv
 
Register the DLLs (click here

2. Reboot your machine. Open a command prompt and run: 
vssadmin list writers 

3. Ensure that all your writers are displayed without errors.

0x80042312: The maximum number of volumes for this operation has been reached. /  0x80042317: The specified volume has already reached its maximum number of shadow copies

Description

The limitation in number of shadow copies per volume is 64. This is the reason that VSS_E_MAXIMUM_NUMBER_OF_VOLUMES_REACHED error occurs when you try to create 65th volume shadow copy. 

When the storage limit is reached, older versions of the shadow copies will be deleted and cannot be restored. There is a limit of 64 shadow copies per volume that can be stored. When this limit is reached, the oldest shadow copy will be deleted and cannot be retrieved.

Cause

The specified volume has already reached its maximum number of shadow copies.

Solution 

Delete the oldest shadow copy for the drive, this should clear out the error. Following is the screenshot and the text of the command:

0x80042313: The shadow copy provider timed out while flushing data to the volume being shadow copied

Description

Check whether the Volume Shadow copy services are started. To start the service, follow the instructions:  

  1. Go to start, type services.msc in start search box and press Enter.
  2. Now, check if Volume shadow copy is running. If not, set it to Start.

Cause

The VSS backups are failing due the high disk activity. High disk activity does not allow VSS to create a shadow copy in the default time period when the volumes are frozen for snapshot.

Solution

Perform the backups when the disk activity is less to avoid third party applications meddling around.

0x80042301: The backup components object is not initialized, this method has been called during a restore operation, or this method has not been called within the correct sequence

Description

A VSS writer depends on another writer on a computer that is running Windows  XP X64 Bit Service Pack 2 (SP2).This other writer has a component list that has no local components.  In this scenario, the VSS writer is not successful when it tries to create a snapshot and you receive the following error code: 0x80042301.

Cause

The VSS returns an instance of the error 0x80042301 (VSS_E_BAD_STATE) if a snapshot does include remote components and does not include any local components.

Solution

0x80042326: The volume being reverted was lost during revert

Description

Sometimes, during the backup process some VSS writers might fail because of time-out errors that cause the backup to fail. A VSS writer is a program or a service that uses the VSS service to save information to a shadow copy storage area.

Cause

You may experience a problem that causes certain VSS writers to time out during a lengthy shadow copy creation. This problem occurs especially on computers that have slow hard disks, low memory, low CPU speed or on computers that have the disk write cache disabled.

Solution

To resolve this problem, obtain the latest service pack for Windows. For further assistance please refer Microsoft KB http://support.microsoft.com/kb/826936

0x80042321: Some shadow copies were not successfully imported

Description

When you use VSS to create more than 10 transportable hardware snapshots in Microsoft Windows XP X64 Bit, some of these snapshots may not be imported within the allocated time. If the snapshots are not imported, the import operation fails.

Cause

This problem occurs because of low time-out values. VSS does not wait long enough for the logical unit numbers (LUNs) to come online. This problem occurs when hardware arrays approach the VSS limit of 64 shadow copies per shadow copy set.

Solution

To resolve this problem, obtain the latest service pack for Windows. The hotfix extends the time-out period to allow for the VSS limit.  For further assistance please refer Microsoft KB http://support.microsoft.com/kb/896592

0x80042320: No shadow copies were successfully imported

Description

When a VSS-based application uses the IVssBackupComponents::ImportSnapshots() API to import a shadow copy that was created on a Microsoft Windows based computer, the ImportSnapshots() call may fail with a "VSS_E_NO_SNAPSHOTS_IMPORTED" error. This issue occurs when the shadow copy was created from volumes that span multiple partitions.

Cause

In a volume that spans multiple partitions or multiple disks, the VSS Service marks only the first partition. Because the additional partitions are not marked VSS cannot later import the shadow copies for the additional volumes.

Solution

A supported hotfix is available from Microsoft which can be downloaded from: http://support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=932532&kbln=en-us

Solution

  1. Check the VSS providers using the following command: 
    > vssadmin list providers
  2. Confirm if there is a 3rd party provider on the machine. If yss, then you will see more than one provider in the output of the above command.
  3. We will now force VSS to always use Microsoft Software Shadow Copy provider by making the following registry entries:
    1. Click Start, click Run, type regedit, and then click OK.
    2. Locate the following registry subkey, and then right-click it:
      HKey_Local_Machine\SYSTEM\CurrentControlSet\Control\BackupRestore
    3. Point to New, and then click DWORD Value.
    4. Type UseMicrosoftProvider as the name for the new DWORD value, and then press ENTER.
    5. Double-click UseMicrosoftProvider. To enable the new feature, type 1 in the Value box. To disable the new feature, type 0 in the Value box.
    6. Press ENTER, and then exit Registry Editor.
  4. Restart the server.

Disclaimer: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Be careful when making any changes to a Windows registry. It is recommended to take a complete backup of the registry and workstation prior to making any registry changes.

Verification

  1. Trigger a backup. The backup will complete successfully.
  2. Uninstall the other software from the device whose provider was being used earlier.
