Windows Server 2016 – Filter Manager Error After Backup starts Event ID 3

More Event Error to tackle Sad smile


Message is a follows :

Filter Manager failed to attach to volume ‘\Device\HarddiskVolume64’. 

This volume will be unavailable for filtering until a reboot.  The final status was 0xC03A001C.


According to this blogpost the reason is simple :

When using the native Backup solution from Windows, and the backup destination is an External Drive.

You can get this error when the Windows Search Service is running ?



Stop the Windows Search Service before the backup starts and start again afterwards.

– net stop wsearch

– net start wsearch



You can incorporate this is the existing Backup Scheduled Tasks like this :

Add one command BEFORE and 1 command AFTER the backup job.



Check the errors afterwards again to see that they are gone.

You can also run devnodeclean before each backup…

Use Task Scheduler with devnodeclean and “switch /r” to remove these phantom volumes.

And stop “wsearch” at the beginning of the backup job and restart “wsearch” after the backup job.

With “devnodeclean.exe /n” you can only display the inactive volumes. The tool needs elevated rights.
