MaxBackups is the number that will be scheduled to run concurrently;
MaxUserBackups controls what you can start manually.  The optimal
value will depend very much on your hardware.  Often running 2
concurrently will complete the whole set faster than 6 due to less
disk head and RAM contention.

A wakeup with nothing to do won't slow your network.  Your production
hours should be in the blackout window.

And, the first wakeup in the list starts the nightly cleanup which
should happen at a time when the backup runs are expected to be
complete.
