Databases that were previously explicitly selected for backup are removed from the MS SQL Server plug-in selection. A back up is then initiated. When browsing the Restore tree, the SQL Server instance is still listed for restore, despite all the databases being deselected from the plug-in backup selection.
Although the databases have been deselected, the SQL Server instance is still selected and present in the backup selection file. As the instance is still present, it is included in the backup process.
Explicitly exclude the SQL Server instance and perform a backup.
