Challenge
Veeam Technical Support has identified that there may be a problem with backing up of the SQL server and/or truncation of the SQL logs. Veeam Technical Support would like to confirm what is configured in SQL and the events that occur during the backup by collecting the SQL logs using SQL Management Studio.
Cause
First open Microsoft SQL Management Studio, and login to the instance Veeam Backup and Replication is attempting to backup.
Once logged in, expand the [Management] folder in the tree view to the left, then expand [SQL Server Logs]
Typically the most current log will be the the most beneficial and it is highlighted in the example above. Double-click this log to open the next dialog box. Look for the [Export] button to generate the log.
Please save the resulting log in either .txt format or .csv format.
When the export is completed, please copy the new log file to either the FTP account supplied by Veeam Technical Support for the case, or or you can log into the Customer Portal (cp.veeam.com) and attach the logs directly to the your case
