You can now connect two Umbrels in different locations and back one up to the other. This already worked on the same network, but the latest Tailscale update in the Umbrel App Store removes the "same network" part. You can now mount folders from one Umbrel into another in Files, even across the world, and use that as a backup location. So one Umbrel at home, one at your parents' place, and tada - you now have real offsite backups, fully self-hosted, on hardware you own. You asked, and it's here!
