Email notification when retry is successful

Sometimes the remote upload fails, but upon second try it succeeds. So the backup succeeded overall, but the job is marked as failed with a message “ERROR: Job has ended with errors in 33 seconds. You must resolve the errors for correct execution.”
This results in alarming email notifications entitled “[ERROR] BackWPup” that appear to show it failed.

Is it possible to consider it successful in this case?
