Full local backup intermittently failing

by davids355 » Tue Nov 18, 2014 1:46 am

I have backup assist V8.0.3
I have several backup sets configured on this particular setup:
5 Rsync backups
1 local disk image backup
they are all set to run at times that don't conflict with each other.

The Rsync backups rarely have any problems, but I keep getting an intermittent problem with the full local backup.
It is set to run daily at 5pm, but every few days it starts to fail.
When it fails I get the error BA2512 unable to create VSS snapshot
in more details it says :
a volume shadow copy service operation error has occurred, 0x800423f3
There is also a related windows log in event viewer:
Microsoft windows backup
the backup operation failed because the volume shadow copy service operation to create a shadow copy of the volumes being backed up failed with the following error code 2155348129

Apparently that is often to do with Sharepoint VSS writer, and tehre is a known issue where Sharepoint needs an update, in this case I have checked for that and it is not the case (checked as per this article: http://support.azuz.it/hc/en-gb/article ... 155348129-).

If I restart the server, the backup will then complete successfully.
I have tried just restarting VSS service, but that does not resolve the issue.

Just wondering if you guys have seen this issue before?

It failed again this evening at 5.30pm.
When it first goes wrong, it often seems to show this message:
BA2507 Another image backup is already running
But the previous backup started at 5pm and finished at 5.05pm.?

Hi There

It's Gagan from the BackupAssist team. Thank you for posting on our forum.

Sorry to hear that you've issues with the backup software.
This error is expressing that a generic error occurred in the backup process and is likely to happen again. This error is typically due to system configuration or other software that prevents the execution of a shadow copy. In order to investigate the core issue, refer to the System and Application event logs from the guest at the time of error.

This error could also occur if the VSS Writer encounters problem while communicating with one or more Hyper-V guests.
You can run the following command from an elevated command prompt on both the host and guest machines: vssadmin list writers

This will list all the writers installed in the system, you can check the ones reporting error.
Sometimes a reboot of the system fixes such issues.

In case you are unable to resolve the issue I would then recommend submitting the diagnostic report for analysis.
To submit the diagnostic report you will need to log in BackupAssist console > Help > Feedback and Support > Contact Support.

We will review the diagnostic report and revert.

Regards
Gagan
