   bs.database_name, 
   bs.backup_start_date, 
   bs.backup_finish_date,
   bs.expiration_date,
   CASE bs.type 
       WHEN 'D' THEN 'Full Database' 
       WHEN 'L' THEN 'Log' 
       WHEN 'I' THEN 'Differential' 
       WHEN 'F' THEN 'File Level' 
       WHEN 'G' THEN 'File Level Differential' 
       WHEN 'P' THEN 'Partial' 
       WHEN 'Q' THEN 'Differential partial'       
   END AS backup_type, 
   convert(varchar,cast(bs.backup_size/1024/1024 as money),10) as 'Backup Size in MB',
   bmf.logical_device_name, 
   bmf.physical_device_name,  
   bs.name AS backupset_name,
   bs.description
FROM   msdb.dbo.backupmediafamily  bmf
   INNER JOIN msdb.dbo.backupset bs ON bmf.media_set_id = bs.media_set_id 
WHERE  (CONVERT(datetime, bs.backup_start_date, 102) >= GETDATE() - 2) 
and bs.type='D'
ORDER BY    bs.database_name,  bs.backup_finish_date desc
