(1/4) Don't be lazy, test your hardware regularly and have checksums of your data.
I have been using #Linux for my servers for many years. Since #Debian Woody to be precise. Later I switched to #Ubuntu Linux. I am currently building a "new" small home server with some old hardware from 2017 and thought it was time for something new: #FreeBSD
The installation and setup went without any problems. #ZFS out of the box. Nice.
