With the following script you can retrieve some of the information relevant for further investigation: Usually, taking a backup changes the database and affects how later backups are restored.
Considering the different elements that influence the outcome of a successful backup operation like backup media, consistency of the backup, network issues if backing up to a UNC pathconsistency of the database being backed up etc.
You will see that the backup completion message has the database name, the number of pages that were contained in the backup, the date the backup was created and the number of devices and their type in this case files. So you can reconstruct the sequence of backups even if your backup information history is missing from the MSDB system tables and you just have your SQL Server Errorlogs to play with.
If you want to get real fancy about this, then you could spin up a nifty little Powershell or VBScript to parse through the SQL Errorlogs and provide the backup sequence to you as well.
Operating system error 3 The system cannot find the path specified. You will notice above that the Operating System error code associated with the backup failure is reported in the error message.
More often than not, the error message is self explanatory. Now that I have finished stating the most obvious of troubleshooting methodologies for SQL native backups which was done to set the context for the next part of this post.
The troubleshooting methodology for non-native backups. Non-native SQL backups of databases use one of the following methods: In this post, I shall not be addressing any storage level backup solutions that have options or features to handles SQL database backups.
If a VDI backup fails, then you can try the following sequence of troubleshooting steps: DLL is updated to the latest build. This check in the tool will perform basic checks like current DLL version and additional checks based on root causes of common scenarios that CSS has seen in the past for VDI backup failures.
Additional information on the usage of the tool is available here. Perform a backup of the database using the tool for which the backup is failing to the same destination if possible. Common errors that you might see during a VDI backup operation failure: Error message 1 BackupVirtualDeviceFile:: Error message 2 Error: Error message 3 Error: If you have an application that uses Volume Shadow Service to backup your SQL database and that backup fails, then you your troubleshooting steps would be a bit different.
In such a failure scenario, take a backup of the database using Windows Server Backup Admin Windows Server and above or NTBackup utility to perform a backup of the database files involved.
If this backup is successful, it means that a snapshot backup is successfully completing for the database. Common errors associated with VSS backups: Check the backup application log for detailed messages.
This error message is raised when your backup application uses VSS to backup a large number of databases simultaneously. More information around this can be found in this post Volume Shadow barfs with 0xe14 code Issue 2 While performing a Bare Metal backup you might run into issues if your SQL Server binaries are located on a different drive other than the C: More information on the same is mentioned here:Numerous backup jobs run by Backup Exec or System Recovery are dependent on Microsoft’s Volume Shadow Copy Service, (VSS).
VSS is used to create snapshots of data that is to be backed up. VSS was introduced with Windows XP and Server Make sure the SQL Server VSS Writer service is up and running (Start-Run -> benjaminpohle.com) and the service logon is NTAUTHORITY/SYSTEM.
If it is a different user, make sure the . MS SQL VSS writer. Sharepoint / Run the command vssadmin list writers at the Windows command prompt and check that the state of the Sharepoint Server Writer is stable.
If not (or if there are any VSS errors), restart the Volume Shadow Copy Service and the Sharepoint Services VSS Writer service.
If the SQL writer is missing and the Application Event log does not indicate an error, confirm the SQL Server VSS Writer Service is added to the sysadmin role in the SQL Server Management Console. If this role was set correctly, check the the database names for the presence of any spaces.
Worked but only after doing something else, not mentioned in the article above Starting SQLCMD without any other parameters only starts it in the default instance of SQL, if you are trying to create an SA account in a named instance (e.g.
sqlServer\sql), you need to connect SQLCMD to that named instance. Not long ago, I had to install SQL Server Service Pack 3 on a multi instance SQL Server. The issue was that SP3 wizard was able to upgrade all the installed services like Reporting, Analysis, and the SQL Server Name Instance but; it failed to upgrade the Default SQL Server Instances.
