SQL Backup issues / Operating system error 995
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.
