Hmmm, when running "sudo run-parts /etc/cron.daily", but prompt goes 
away for a few seconds and comes right back; nothing new created. Backup 
on this box usually takes about 30 + seconds.  I assumed cron's schedule 
was satisfied for the day, so wouldn't run it again.

Running anacron also returns pretty quickly (under 5 seconds):

don at johnny:~$ sudo anacron -n -d -f
Anacron 2.3 started on 2019-11-24
Will run job `cron.daily'
Will run job `cron.weekly'
Will run job `cron.monthly'
Jobs will be executed sequentially
Job `cron.daily' started
Job `cron.daily' terminated
Job `cron.weekly' started
Job `cron.weekly' terminated
Job `cron.monthly' started
Job `cron.monthly' terminated
Normal exit (3 jobs run)
don at johnny:~$

I'll let you know if it creates one overnight,

Don
