I have lived in an apartment that caught fire, a house where the basement flooded, another basement apartment that suffered frequent flooding whenever it rained, and just when I thought I was safe in a 20th floor high rise the sprinkler system malfunctioned and flooded several floors.
I've been fortunate enough to avoid catastrophic data loss from these events, but I've been wanting to set up a 3-2-1 backup strategy before my luck runs out. This means having three copies of your data stored on two different forms of media (like an external hard drive or another ZFS storage pool) and importantly, one copy off-site.
This article will focus on the off-site portion, and I've settled on BorgBackup to a remote Raspberry Pi.

Simple screen sharing over LAN using a RaspberryPi or display computer connected to a projector or TV.

Monitor and control all your smart home devices via a unified web interface. Build your own smart hub on a rPi or on a Turris Omnia router.

This new release comes with support for thermostats and smart locks, as well as an updated add-ons system including extension add-ons, which enable developers to extend the gateway user interface. There are also localization settings now so that you can choose your country, language, time zone and unit preferences.
