I second this suggestion.  Cleaning the pool (what BackupPC_nightly does) *thrashes* the disks, pretty much causing your backups to pause during the time in which this runs.  I move mine to 10 A.M. (by making the first entry in the WakeupSchedule be 10:  10, 1 , 2, 3, ...).

As for leaving 0 (midnight) out:  I'm actually a fan of this.  Too many things are triggered at the change of the day that I never knowingly schedule anything for midnight for performance reasons.  Plus, there is confusion of when exactly midnight is:  is Midnight at the beginning or the end of the day?  I've seen it both ways...  So, personally, I simply avoid it.

Of course, I often take this farter and never trigger things for the start of an hour, even.  I usually go with 7 minutes after the hour just out of general principle.  Seeing as BPC can't start on not-hours (or, at least, I've never tried a fractional hour within the WakeupSchedule), I don't mind skipping midnight...

But don't let my foibles prevent you from starting on that extra hour!  :)
