NTFS event Error during backup BE2012.

Hi there.

I'm running Backup Exec 2012 fully patched, primary backup of VM Ware virtual machines.

Last week we suddenly see this error ind the EventViewer on the backup server and backup started to fail and some jobs startet to take much longer time than normal. I have triede to find a solution, but no luck.

The error from the eventviewer

The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume .

We have run chkdsk [driveletter] /f on the backup server, but no error reported.

As you can see there is no indication in the error, that shows us which drive its regarding.

Hope someone can ghelp me.

Best regards

Dennis

You should run chkdsk on the volume that you are backing up, not the media server.

Yes it is event id 55 but i

Yes it is event id 55 but i have found out that it is when backup of some windows 2012 virtual servers.

Run chkdks on one of them and no problems there.

Does the event 55 generate

Does the event 55 generate each time when the backup fails ? (Though its a bit uncommon that the event does not specify which volume). Are there any corresponding errors under the Application events when this system event occurs ?

What is the Backup Exec error which you receive from the job log ?

Lastly, are you backing up to disk or tape ? If disk, has chkdsk been run on this storage as well ?

Yes each time, but there is

Yes each time, but there is no error in the job. No corresponding errors under application events.

The backup is to a deduplication store and chkdks have been run on this drive.

I have installed this hotfix http://support.microsoft.com/kb/2754784 now i'm trying to run backuop again.

I will report back with the result.

Hi The hotfix didn't help,

Hi

The hotfix didn't help, the Event 55 is still in the event viewer. But backup run fine and done some restore test.

Dennis

any updates on this one? i

any updates on this one?

i have the same problem when backing up VMs over SAN.

running 2012 SP3 on all media servers and caso.

If this only affactes Windows

If this only affactes Windows 2012 virtual servers, as we mount the vmdk files in order to catalog the file system GRT, it's possible that this error is being generated because the operating system of the media server briefly sees the disk system that is held inside Windows 2012 as if it is a local disk.

 

If it only does the error for some but not all Windows 2012 VM's then try looking at differences in the configurations of the vmdk files and the windows volumes held within the vmdk files between VMs that appear to generate the error and those that don't, it's possible you may find somethingn that is not supported yet.

 

BTW I'd ecnorarge formal support cases to be logged for this issue just for us to confirm what is happening as my comments above are a theory / educated guess.
