yes i have tried in T-SQL also using following command
RESTORE DATABASE <YourDatabase>
FROM DISK='<the path to your backup file>\<YourDatabase>.bak'
But i am facing following error.
Msg 3241, Level 16, State 7, Line 1 The media family on device 'D:\dummy.bak' is incorrectly formed. SQL Server cannot process this media family. Msg 3013, Level 16, State 1, Line 1 RESTORE DATABASE is terminating abnormally.
I have tried to restore this database backup in SQL server 2005 itself. At that time backup set is able to select for restoring.
