It's hard to say what's wrong there. You need to look above in the backup log, most likely there will be more errors or warnings. That that you see - result of that in xml there is a link to archive which is not present for some reasons.

It is most likely a temporary error. It may occur when two backups run at the same time.

Thank you both for your support!

A manual full backup followed by a manual incremental backup both worked. A test restore of the full backup to another machine first did not work, but that is a different issue. On further attempts, the test restore did work, too. So, yes, probably in this case it was a temporary issue.
