I have no personal experience with ibeezz, but this shareware application ($15.00) may be a solution-adanced sleep settings and 3.5 stars at MacUpdate. Free 30 day trial.

What seems nice to me, is that it will wake your machine at X time so that backups, etc. can be run, and then put it back to sleep when the BU is completed.

And if you do get iIbeezz, please post your review. I may even get it. cool
