I have a couple of 6tb usb disks formatted as a Btrfs RAID 1 volume plugged into a Rpi4, it's not the fastest but it has been reliable for over a year. I always make sure I stop the backup before pulling the cord on my laptop though. My wife hadn't been doing this until recently and she has had more problems with both over the network and directly connected usb disks; she has both. At some point I'm going to create a duplicate setup in my house and send Btrfs snapshots over the internet to have an offsite backup, but I haven't got round to this yet. Currently our offsite backup is just taking a laptop home...
