Is your actual backup program started in background by run-backup.sh
and script itself exits? Because that is what is implied by
Type=forking. If yes, it apparently takes over 30 seconds as systemctl
is killed by udev. You probably want to use "systemctl --no-block" in
this case.

Hard to tell without systemd debug output. You can enable it online by
sending signal to systemd, see man page.
