Are you trying to back up ot the same server or a dofferent one? Do you have the requisite permissions to do this?

why backup to a .mdf? that's confusing. use a .bak extension for your file like int Abhinav's sol'n

Picking up the example from here[^], you should be able to point to the exact location (path) in the TO DISK section of the statement.

SQL

USE AdventureWorks2008R2;
GO
BACKUP DATABASE AdventureWorks2008R2
TO DISK = 'Z:\SQLServerBackups\AdventureWorks2008R2.Bak'
   WITH FORMAT,
      MEDIANAME = 'Z_SQLServerBackups',
      NAME = 'Full Backup of AdventureWorks2008R2';
GO

Looks like either the path in filename is incorrect, or you may not have the appropriate permissions.
