VSS Failed Windows 2008 R2

Post by bluecoffee »

When backing up a windows 2008 r2 server this is a DC and also running exchange I get the following error. Veeam backup ver.5.

Code: Select all

Freezing guest operating system
VSSControl: 0 Backup job failed.
Cannot create a shadow copy of the volumes containing writer's data.
Cannot prepare the [NTDS] data to a subsequent restore operation.
Cannot process NTDS data.
Cannot create a backup copy of the BCD.
Can anyone provide a pointer for me?

From the error, it kooks like some Microsoft VSS framework issue to me. First troubleshooting step should be running the following 2 commands on the affected VM, and investigating output for any issues. If any issues are present, best would be to open support case with Microsoft. But before doing that, you may want to search for, and uninstally any 3rd party VSS writers and providers (these are usually installed with different backup/DR tools "agents").

Code: Select all

vssadmin list writers
vssadmin list providers

Backed up server with application aware off. Backed up fine. Turned back on, error disappeared and backup completed.

Hello Matt, thanks for the update! Even though you have successfully backed up this VM, I would recommend checking Windows Event log to see what was the reason for the previous failure. Having done that, you might be able avoid the same errors in the future.

The solution for this is to enable disk auto mounting. Open a command window with elevated privileges and run:

diskpart

Check the status of auto mount by typing automount into the DISKPART window.

Automatic mounting of new volumes disabled.

Enable auto mount by typing automount enable

Type exit

Reboot.

Just make sure you do not try and do this on your Veeam Backup server running jobs in Direct SAN Access or Virtual Appliance modes. Since automount is enabled by default in Windows, I am guessing you might be talking here about Veeam Backup server (as our setup program disables automount automatically to prevent Windows from corrupting VMFS datastores and backed up disks respectively by re-signaturing them). Thanks!

Diskpart fix solved the same issue for me as well. No idea why it was disabled and Veeam never suggested this. Thanks guys!

I got this exact same error on a Win2k8 R2 and it turned out the C: drive was running low on space so that's an additional thing to check. Once I increased the drive space the error went away.

Ah, that's is right, I heard before that VSS is affected when there is very low disk space on the volume. Thanks Kenn for sharing this.

Legend, that resolved my issue as well, funnily enough only seems to have affected DC's so far for me. - Thanks!

I know this thread is a little old, but I wanted to add to it and say that automount was an issue for me as well on a 2008 R2 domain controller. Enabling it solved the issue. I am running 6.1 with update 1 installed.

I had two domain controllers at a customer with exactly same issue.

I never said anything about Windows event log... it is Veeam's guest processing debug log that contains the required information.

Please, open a support case for further assistance. Even if I tell you where you can find those logs, your next post will obviously be "OK, so how do I make sense of them" :D and we don't do log research through the forum posts.

Worth noting that I was getting this error because the system drive had run out of space. HTH
