I didn't get any email reporting backup errors, although: - I have an admin email sent, and I get overquota emails, and certificate delivery errors emails. - I have set the option to send warning or worse emails notification for any server.

Sorry, what you mean "this ISPConfig version"? You mean the last stable version? That I have an outdate version on my server? Honestly, I have never seen a backup error notification. I use to discover backup errors on my weekly check. What can I do to continue troubleshooting this? Thanks a lot.
The last ISPConfig stable version is ISPConfig 3.3.1. According to your post, you run 3.3.0p3, so you are not running the current ISPConfig stable version. The backup system has undergone a lot of changes in the recent stable version.
I have updated to version 3.3.1 all servers. I generated a backup error and it is sent to email now. It seems that the update works! Thanks.
The problem persists, I have isolated it a bit more. If I stop cron, launch a backup and run manually server.sh the error is generated and the mail is sent and received ok. When the task is executed from cron, at 3:15am daily, the error is generated but the mail is not sent. That has been checked with mail provider, there is not an attemp to send mail from their side at 3:15am. They have logs from manual attemps. Thanks for your help.
First, you should check the mail.log on your server to see if a sending attempt is made. Then you can try to use the cron_debug.php script to simulate a backup run. I can't say for sure which exact error emails are sent in case of a failure. If you want to know it in detail, you might want to take a look into the code.
Please can you detail how to exactly use cron_debug.php? If I use php cron_debug.php --cronjob=500-backup.inc.php, will it lauch all backups for all sites? Thanks.
Is there any way to restrict this to a single site? Cause runing a test run for more than 100 sites is complicate.
No, at least not without changing the backup code. You tested the single-site backup, and it works according to your posts.
