Database backup not working

I’m just starting the process of moving from a very old Mac mini to a slightly less old MacBook Pro.

I’m following the instructions here: https://getchannels.com/docs/articles/migrate-dvr-to-new-computer/

I’ve come across a problem right at the start. For some reason my existing installation of Channels isn’t backing up properly. It says it hasn’t backed up 2019 years!!!!. I’ve checked and there is one from a few days ago, but it has definitely stopped in recent days.

What can I do to force a back up? Clicking on the back up button does nothing.

OK, i’ve restarted the Mac mini (previously tried just restarting channels) and it seems to have fixed it.

Weird bug though.
