So again, I stumbled with following errors in smsbkup.log, “After DoSnapshotSet SQL Writer status = FAILED_AT_FREEZE”  and “Error: VSS_E_WRITERERROR_NONRETRYABLE. Error Code = 0x80,042,3f4“. Now what? Back to basics, in SMS 2003 days, during SMS back up, all the other SMS-related services used to be in the stopped state. This is changed in SCCM 2007 with the integration of VSS.

In my Scenario, SMS backup could not stop the “SMS Executive” service. So, where did I get the clue about this? Again ConfigMgr Admins best friend, the log files.

In my case, it was smswriter.log. In smswriter.log, I was able to see that the SMS Component Manager service was stopped successfully, and the next step that was supposed to happen was stopping the ‘SMS Executive’ service. But the backup could not stop the service, and it was getting timed out.

Now, as a workaround, I’ve manually killed smsexec.exe (exe for SMS Executive Service) from the task manager while it was in a stopping state. That is it !! Wow!! This resolved my backup issue. The backup was successful.

Yes, if you noticed above, I had already mentioned that the primary server had some communication problems with secondary sites (some of them), and the primary server had a very bad backlog.

The problem was SMS Executive service was very busy processing those requests, and hence the backup service was not able to stop the SMS Executive Service.
