Nothing. I think that the only program I ever bought was some incremental backup software for Windows XP for my laptop at home but that was some years later, in the 2000s. For everything else, free or open source solutions were good enough for me even when I still used Windows. By the way, I'm using rsnapshot for my backups now.
