SQL SERVER VDI CODE
You will notice above that the Operating System error code associated with the backup failure is reported in the error message. Operating system error 3(The system cannot find the path specified.).īACKUP failed to complete the command BACKUP DATABASE adventureworks. Now, let’s look at a failed backup message from the SQL Errorlog.īackupDiskFile::CreateMedia: Backup device ‘R:\adventureworks.bak’ failed to create. 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. 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. 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). Database: adventureworks, creation date(time): 8(03:00:18), pages dumped: 17291, first LSN: 67:7733:56, last LSN: 67:7761:1, number of dump devices: 1, device information: (FILE=1, TYPE=DISK: ). I shall attempt to outline a set of troubleshooting steps specifically for non-native backup/restore related errors for SQL Server databases.Īny BACKUP command that completes successfully or with errors has associated messages logged in the SQL Server Errorlog.Ī successful backup from the SQL Server Errorlog:ĭatabase backed up. 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 path), consistency of the database being backed up etc. The latest release can be downloaded here.īackup and restore operations even though they are supposed to be a no-brainer, it can leave you wanting to tear your hair out. The incorporation of this feature will be evaluated while planning for the next release.Ī big thank you to Sakthi for his assistance on the v2 release.

Log Restore option is not currently available in this release. Server Default: This option uses the server default setting (configuration setting: backup compression default) to perform the backup. No Compression: This option will allow you to perform a backup with compression disabled even if the server default is to use compression for backups.Ĭ.

Log backup – Now the tool can perform log backups.Based on the feedback received from the use of the tool and the current troubleshooting needs, we decided to do v2 release for SQL Server Backup Simulator.
SQL SERVER VDI SIMULATOR
SQL Server Backup Simulator is used by CSS to troubleshoot SQLVDI related issues and to identify if the SQLVDI DLL is functioning correctly.
