systemd tracks everything - system calls, signals, exit codes during execution of a service. Fortunately, it still things SIGPIPE is "okay". systemd also tries to guess what is the "main" process of the service, it tracks (among others) forks and may believe /usr/bin/tarsnap binary is the "main" and the most important process indeed and track its exit code instead. https://lists.debian.org/debian-user/2016/10/msg00422.html Can you try setting GuessMainPID=no in the [Service] section of the unit file?
