if you have a recent system, then chances are high that you are using 
systemd as init. In this case you could simply run the script from a 
timer, instead of cron. This gives you the desired behavior for free. 
Systemd will ensure that only a single instance is running at a time.

If you have a working setup, you can stick with it. If you set up a new 
server, you might want to use the script.
In case of partial updates, you might need to check your specific 
use-case. Mine was not covered well.
