Monthly Lockup?

Anyone else have monthly high-CPU usage?
I have alerting from the VM setup, and I get high-CPU warnings maybe once a month (>70% for over 10 minutes):

Here’s the CPU spike:

It corresponds with a monthly spike, and subsequent fall, in disk usage:

I’m wondering if it’s something to do with fail2ban?
It’s the only thing that sticks out, processing time-wise, using ps awlx:

3 AM — do you have a lot of domains/users? 3AM is the time of day that reports and daily tasks are run. I do not know if there is a specific monthly task though…

This server actually only hosts two users.

Doing some digging, it appears to be the local Full Backup that’s generated every month. I guess that’s case closed.
