SQL Server 2008 and SQL Server 2008 R2 have this problem according to some pages. These are areas for you to check, though I am unsure of the technology you are using.

One easy problem to look into is: How much Disk Space Available for Backups


Includes a note saying: After cleaning up old backup files I re-run the backup job and it succeeded.

Some other entries that seem to cluster around the problem can be found below.

• Troubleshooting VSS Writer issues

• How to troubleshoot "Msg 3041" in SQL Server

And an example from a specific vendor, Commvault:

• SQL backup failing with SQLQUERY Failure or VDITimeout

I do not have specific experience with this, but I see a few posts that have not been answered successfully, so just pointing you to other resources.
