I have four computers that I use personally on a regular basis: A laptop (spock), a home server (hestia), and a VPS (picard), all running various Linux distributions; and a smartphone (alm-ios-04), unfortunately an Apple iPhone (if a miracle occurs, it may someday be replaced by my Librem 5, scotty). I need to back up these computers so I don't lose their contents in the event of some kind of problem with them. In the rest of this article I'll discuss how I handle that.
