@Pepijn it does actually, if you make backing things up easy enough.
This is super nerdy, but I have an entry in my monitoring software that expects at least one manual backup per week. "Manual" means that I have to take a USB drive and plug it in. With some Linux magic, once this exact drive is plugged it, it will automatically start a backup job and send me a push notification when it's done and tell my monitoring that a backup was created.
If I forget about it, I'll get nagging reminders until I do it.
