V-79-10000-11226 - VSS Snapshot error - How to prevent it?

Created: 01 Feb 2013 | Updated: 08 Apr 2013 | 5 comments

This issue has been solved. See solution.

I'm running Backup Exec 2010 and we will occasionally have a backup fail on a machine (not always the same one) with the error message:

V-79-10000-11226 - VSS Snapshot error

(I can provide the full text of the error message if needed)

After some research, I found this article on Symantec's web site:

http://www.symantec.com/business/support/index?page=content&id=TECH77585

That fixes the problem and backups run on whatever machine had the problem, but that leaves two big questions:

1) Is there a way to test for this problem without having to actually run the backup?

2) Is there a way to prevent this problem from popping up at all?

This seems to come up rather frequently for us and it's pretty random, which is making it very hard to track down, so any help would be greatly appreciated.

Thanks!

Bryan

Hi,

If you provide the full text of the error message then it will be easier to find the solution.

Hi Bryan,

1. there is no way to test whether or not the VSS provider will fail. You can try scheduling a test run, but not sure this will even work. This is unfortunately something that happens when VSS is called by the backup.

2. Not really...make sure that your VSS provider is set to Automatic in the job setup and see if this fixes the issue.

Thanks!

If you find this is a solution, please mark it as such.

Hi Bryan,

Or make below changes and verify......

In the job Properties, Under Settings, in Advanced open file option make the following changes :-

A) Set Open file Configuration to Microsoft Volume Shadow Copy Service (Windows 2003 and later).
B) Select the Snapshot provider as System - Use Microsoft Software Shadow Copy Service Provider.

Then Run the job.

Thanks.

did you ever had BESR running on the servers where the above problem is seen ? The reason I want to know this is that everytime you would not have to delete those GUIDs. Is the document really helping you resolve the Issue or just a simple reboot of the server fixes the Issue.

You can schedule a script to run vssadmin list writers command and keep appending to the same output file. If you run into the error check the output file to see if any writer had become unstable or was in failed state. If that is the case next time would know if any writers failed , you can reboot the server and then let the backup run.

The above would involve manual work.
