How To Shut Down BACKUP APPEND Mode?

Hi All,

I got a job which runs every day this T-SQL code:

BACKUP DATABASE [myDB] TO DISK = N'f:BACKUPSDailymyBKUP.bak' WITH NOINIT , NOUNLOAD , NAME = N'mybackup', NOSKIP , STATS = 10, NOFORMAT

It runs just fine but in append Mode (the default one); the bak file is being taped every night, so I would like to overwrite it, in order it not to become huge after a few time, but I can't seem to find a clear way to do this.

Any help or pointing would be appreciated!

Cheers,

Giovanni
