SuperDuper! Scheduled Backups

Still waiting for a good stable version of SuperDuper for Leopard, and for the MP to arrive, but I have a question...

SuperDuper has a scheduled backup option. Great, simple enough.

Is there a way to have a machine wakeup, run the scheduled backup, and then sleep when complete?

Basically I'd like to have a backup run nightly, but wouldn't want to leave the machine on all night to accomplish it.
