Welcome to the forum @guemi
In addition to an issue (or at least a forum topic), workaround might be in third-party monitor such as
Duplicati Monitoring that knows expected backup schedule and independently sees that it’s followed.
Discussed by original developer recently here, basically talking about the risks of starting a business. Thanks though for being another voice that speaks to the idea of the missing middleground problem, which would be another good discussion topic. As you may note, I’m trying to keep this a bit on-topic.
I’d love to talk more about both ideas, if you’d care to move them. If you do, we can edit here to point.
