Scheduling backup for the 5th week of the month?

[noamb]

Hey all,

I want to schedule two backup drives that'll rotate weekly.

However, there's no option in the Scheduling window for what'll happen in the fifth week of a month.

What *will* happen?

Thanks,
noam

Week 4 and week 5 are combined. (The weeks are days 1-7, 8-14, 15-21, 22-31.)
