I use Syncthing on my PCs and NAS, and Backblaze to trivially do a 3-2-1 backup strategy. My work directories are synced on all devices. With my NAS up 24/7, I can always pick up the last changes when I switch computers. The irreplaceable documents (all my notes, taxes, company accounting,...) are also backed up by the NAS on Backblaze, keeping all versions. I occasionally create a snapshot on Backblaze for those files – should totally automate that but I'm lazy. I do agree though: it's more "syncing stuff between multiple places" than a real backup.
