I need to create Daily, Weekly and Monthly backup

Hello Everyone, 

Here is our scenario, 

Week A ==> Mon, Tues, Wed, Thurs,Friday, Saturday, Sunday

Week B ==> Mon,Tues,Wed, Thursday, Friday, Saturday, Sunday

Last Sunday of the Month: - Monthly Backup of either week A or B.

We wish to setup Daily backup and assign each slot a Day.  E.g Mon=Slot 1, Tues, Slot 2.  After which it will need to make the backup each day but on the next following week, it will need to change to Week B.

We wish also that on every last Sunday either being on Week A or B, it makes up a full weekly backup.

Finally the last sunday of each month the montly backup.  depending which will be in the library. 

Can anyone guide us or is there any other better way of doing Daily, Weekly and Monthly but keeping in mind we need a minimum of 2 set of tapes.

Thanks
