What you want to do is add a scheduled task for SQLServerAgent, and let it do the backup on a scheduled basis. If you have enterprise manager, use the database amintenace wizared to create the backup jobs. If not the TSQL code below will create a weekkly backup schedule, rotating the backup file name and overwiting the oldest. (there is a better way to do this, sql can manage the retention for you, but this is all I had handy)
