I finally built a real 3-2-1 backup system for my homelab.

It ended up being way more than just “set up backups”:
offsite TrueNAS, a rebuild of the main NAS, and a third copy on a different platform for easier restores.

~30TB, no giant cloud bill, and a much better recovery story now.

Last night I had a dream that I traveled back in time to 2003. I couldn't figure out where I parked my DeLorean so I was stuck there.
The scariest thing about being in 2003 in my dream was that when I looked at my phone it said I was connected at 3G.

I decided to start with the easiest fix, cutting and re-punching the living room keystone jack. And sure enough, the cable tested clean and the anomaly no longer shows up on that port. It is still showing in the 24-hour AI Anomaly Score, so hopefully that drops off tomorrow!

So I pulled out my network tester. It showed that pins 7 and 8 were missing or wired incorrectly. I checked the server room end first and it looked good. Then I checked the keystone jack in the living room and that looked good too.

A little backstory...
For a few months, my switch had been warning that my connection was degraded and telling me it was probably bad wiring. But the device was still negotiating at 2.5 Gb/s and receiving PoE power so I kept thinking, "There is no way that's right."

Today I decided to clear the error because I was sure it was wrong, but every time I cleared it, it came right back. I even went as far as remoting into the switch and clearing it via the CLI, and it still came back.

After a month of troubleshooting my network, it ended up being a loose connection. Such a great sight to see!
