How to create a database backup replacing the previously created backup file

backupsql-server-2008tsql

If I backup my SQL Server 2008 R2 database with the following command

set @BackupFileName = N'C:\backup\Production-db.BAK' BACKUP DATABASE
[Production-db] TO  DISK = @BackupFileName

and run the command twice, the backup file grows to twice the current database size. With every new run, additional data is appended.

How can I create a full backup without appending, but by replacing the previous backup file?

Thanks,

Adrian

You should specify the FORMAT clause to overwrite your media set. See the following MSDN article for more details: http://msdn.microsoft.com/en-us/library/ms191304.aspx
