This command is an Intel NUC on the local network, and /srv/backups is a Btrfs formatted volume.

$ sudo btrfs send -p home.20220810 home.20220815 | ssh chris@fnuc.local "sudo btrfs receive /srv/backups/fovo/"

Although when I'm traveling it looks a bit differently because I'll use a locally attached USB stick:

$ sudo btrfs send -p home.20220810 home.20220815 | sudo btrfs receive /run/chris/backups/fovo/


Because the "root" subvolume contains everything, including logs and VM images if you use virt-manager, databases, it can actually go through quite a bit of churn. Probably more than the typical "home".
