I set up a directory for Plex Media Server to store database backups to, and it's set to occur every three days. I've now waited a full week, and nothing has been backed up and stored in that directory.
I looked through logs but couldn't find anything related to a backup task. Then again, there were so many different logs to sort through, that it's possible I just wasn't even looking in the right log.
plexmediaserver is running as root, and I can touch
anything in that directory, so I know it's not a permissions issue.
