    SSMS Tools Pack

    I recently ran into this great tool. SSMS Tools PACK is an Add-In (Add-On) for Microsoft SQL Server Management Studio and Microsoft SQL Server Management Studio Express.

    It contains a few upgrades to the IDE from the Management Studio:

    SQL Server 2008 - calculating backup ratios

    Backup compression is one of the coolest new features in SQL Server 2008. This nice little query gives you an overview of the average compression ratios. I used another T-SQL enhancement (GROUPING SETS) to show the ratio per database, backup type, ...


    SELECT
    DatabaseName =ISNULL(database_name,'(All Databases)'),
    BackupType =ISNULL(CAST(type AS VARCHAR(15)), '(All Types)'),
    CompressionRatio = AVG( CAST(backup_size/ compressed_backup_size AS DECIMAL(5,2)))
    from msdb..backupset
    WHERE (backup_size <> compressed_backup_size)
    GROUP BY GROUPING SETS((database_name,type), (database_name), (type), ())
    ORDER BY 1,2
