With "doveadm backup" you have gotten into such a state that the INBOX needs to be deleted and recreated to preserve it exactly as it's in source. But you're using Maildir format, which doesn't allow deleting INBOX. So possibilities: a) Don't use Maildir format b) Delete the entire Maildir manually with rm -rf and the next doveadm backup should work (if not then something strange is going on)
