Creating Job To Do Daily Backup

I have a client that is using the free MSDE database engine. There is no graphical interface that I know of to manage the day-to-day tasks. I need to do a daily backup to a disk file. I want to start the backup at 7:40pm. My client then will copy that disk file to tape duing his system-wide backup at midnight. I setup a batch file and executed it in osql but the job is not working. No disk file has been created in the last 3 weeks. I don't have a clue what I am missing. Can someone please look at this and tell me how to fix it??

Thanks in Advance!
