Automatic backup fails


I’ve setup two virtualmin servers with automatic backups - one to an FTP server and the other to S3. Both fail to run on schedule (daily in this case). However if I click on the back up and do “Backup Now” or “Backup in the Background”, it works fine.

I included a screenshot of the setup.

Here’s the error I get

[code]Backing up mail and FTP user Cron jobs …
… none to backup
