The first cut will be which ones have reached their backup interval 
(since the last backup) at each wakeup time.  That is, at each wakeup it 
will consider only the set that is not within a blackout and has passed 
the interval time since it's last run - and these will not start if the 
ping test fails.  I'm not sure who wins if there are more choices at one 
time than your concurrency limit allows - it might just be the order in 
the host list.  I just start one early from the web interface if I want 
to push it ahead.
