Backup failed with permission denied

[spongeleopard (dave)]

I’ve been using Discourse successfully for a while now, but backups have all of a sudden stopped working.

Relevant line from the log is below. Not sure what would have caused this permission error to start happening from out of the blue. I was going to start mucking around, but thought I’d ask here if there was an easy known fix.

I’m having the same exception. Did you get a fix?

I probably won’t get to investigate further for a couple of days.

Here’s the exception with #### used to edit out private info:
