(not a contributor) but I got caught out by that as well. From the code, (I think) it's only sending a notification if the backup failed and it seems intentional.

Some way to test this would be great, either an option to send a mail on success too, or a cli command in the container or whatever. I can tell that echo Test | sendmail -f noreply@mydomain.net me@mydomain.net works but who knows if that's also true for the notifications. One simple way to test it by provoking an error is to set the /backup mount to ro.
