Restore Database script I have a live database which i would like to create a backup and restore script that will take the "live" database every night, create a back, then drop the existing "testing" database (if any) and restore the same .bak file (on the same server) into a new database, this way, i always have the most up-to-date database to test on. 

here are the steps:


back up database ABC (call it abc.bak)
drop (or clean/clear) database abc_test
restore abc.bak into abc_test


Please let me know if anyone know or have a script that does so.

Thanks!
You could set up a simple job to backup the database to a single location and then restore it. It would look something like this

--First we back up the DB        
BACKUP DATABASE [ABC] TO  DISK = N'C:\temp\ABC.bak' WITH NOFORMAT, NOINIT,
        NAME = N'ABC-Full Database Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10
        GO
--Then we restore the DB
        RESTORE DATABASE [ABC_test] FROM  DISK = N'C:\temp\ABC.bak' WITH  FILE = 1,  MOVE N'ABC' TO N'C:\DBFiles\ABC_test.mdf',  
        MOVE N'ABC_log' TO N'C:\DBFiles\ABC_test_log.ldf',  NOUNLOAD,  REPLACE,  STATS = 10
        GO


You might want to delete the file before you back it up. You could do this with powershell (my recommendation), xp_delete_file (undocumented SP), or xp_cmdshell (not sure if it is enabled on your system or not)
