Open SQL server and write following query;

  1. SELECT a.Name AS [DB_Name],  
  2.   
  3. COALESCE(CONVERT(VARCHAR(12), MAX(b.backup_finish_date), 101), '-') AS LastBackup  
  4.   
  5. FROM sys.sysdatabases a  
  6.   
  7. LEFT OUTER JOIN msdb.dbo.backupset b ON b.database_name = a.name  
  8.   
  9. GROUP BY a.Name
