That was my thought - I'd been setting up a .timer and .service to
invoke the shell script, but they failed because the script wasn't
executable.

In this case, systemd was definitely smarter than the sysadmin.

Upon closer inspection of the crontab, I noticed something I'd overlooked.

The folder is where a lot of backups reside, and I wanted them to be 
root owned and chmod 0600 for extra safety.

This was set to happen every minute.

Must have been something I setup during testing and forgot to change?

Or was just being dumb, should have run chmod g-rw,o-rw instead. And, 
added that to the end of the backup script(s).
