Job has ended with errors

I have this problem when trying to do a backup of my wordpress site with BackWPup.
I am using the FTP account, I already set the Maximum script execution time in 25 seconds and the Maximum number of retries for job steps in 3.
I just replaced here some values by “XXX” to hide private data.

I look forward to your guidance. Thanks.
