Privacy conscious people: we can still use your preferred private super secretive way to pay for important stuff, and use PIX for a Coca Cola. One thing doesn’t stop the other.

Every night, for about 10 minutes, the connections from our HQ to a relay tower became flaky. At the time we were using two Mikrotik 5GHz cards and some large antennas.
You could sit in front your computer and wait, a few minutes after the sunset, for the monitoring alerts start arriving. After a week trying everything, including changing hardware (to the same specs), I was very disappointed with the thing and got out to smoke around the sunset.
Then some huge lamps we had around the building switched on, based on a light sensor. Immediately I received the SMS alerts on my phone. I ran into the building, turned off the external lights and bingo: 0% packet loss.
It turns out that the building management had changed all of external lamps the week before, with new sodium-vapor bulbs. And for some reason, on the first 5 to 10 minutes with these lights on, it caused very high interference on the 5GHz band.
Changed the lamps, problem solved.
It's on the paper.
On this size class (~1TB) I see PITR backups using something like Barman as the only viable alternative. (Of course you can also copy the whole VM/Disk etc)
