Is there a way of testing or seeing that the job has run successfully like a system log or something.
If you did not enable the "quiet" option, you will see in the system logs which files have been copied. For this select "rsync" in the system logs view.
You can also enable the "send e-mail" option to receive an email after. Works only if you have configured notifications.
Finally you can use the terminal to check if all files are there.
