Error Code 6:64 System State Backup of component failed

Article ID: AD0020 System State only backup hangs at 25% to 70% and shows no progress. If the System State is being backed up by the default subclient, the backup will hang at 75%.

Symptom

For Versions 7.0 and 8.0 the "clbackup.log" and for Version 6.1 the "W2dbBackup.log" for Versions 6.1 the following will appear at the end of the log for the job having the issue:

<--- ADDING COMPONENT --->

5600 1474 07/08 09:45:31 {Job ID} Entering [CWinBackupJob::AddComponent]

5600 1474 07/08 09:45:31 {Job ID} Entering [CWmiBackup::GatherActiveStatus]

For Version 9.0 and later the following message may appear:

Error Code 6:64

System State Backup of component [...] failed.

Cause

Occasionally WMI service can hang when trying to register system performance libraries. When the Backup Software queries the operating system for the status of WMI, no response is returned causing the System State backup to hang indefinitely.

Resolution

Depending on the Windows OS version you can run the following command to register the system performance libraries with WMI.

Windows 2008, Windows 2008 R2:

Resyncing the counters with Windows Management Instrumentation (WMI):

WINMGMT.EXE /RESYNCPERF

Windows 2003, Windows XP, Windows 2000:

wmiadap /f

Windows 2000 and NT:

winmgmt /resyncperf <winmgmt-service-process-id>

For more information on above commands, please refer to the following Microsoft articles:

If these methods fail then a reboot of the server is strongly recommended.

Work Around

By default, the system state is backed up along with file system data by the default subclient of a Backup Set.  A system state backup is always a full backup whether you select full, incremental, or differential backup for the subclient that includes the system state.  You can, however, filter out some components from system state backup.

1. From the CommCell Console, navigate to Client Computers | File System | Backup set.

2. Right-click the subclient in the right pane and click Properties.

3. Click the Filters tab.

4. Click Add from the Exclude these files/folders/patterns group.

5. Enter the path within curly brackets. Following are the entries that can be made:

? {Active Directory Application Mode}

? {Certificate Services }

? {COM+ Database}

? {Content Indexing Catalogs}

? {DHCP}

? {Disk Quotas}

? {File Server Resource Manager}

? {Event Logs}

? {IIS}

? {NPS Database}

? {Offline Files}

? {One Touch Files}

? {Remote Storage Database}

? {RSM}

? {System Protected Files}

? {Terminal Services Licensing}

? {UDDI Database}

? {WINS}

? {WMI Database}

6. Click OK.

7. Click OK to save your changes.

For each additional component that you want to exclude from backup, click Add and repeat Steps 4 and 5 of this procedure.

When you have finished selecting components to be excluded from backup, click the OK button to close the Properties dialog.
