Sorry for hijacking this old one, but I think I have the same question as Eber_Aparecido_ and I am still looking for an answer.
Using the scheduled backup (System Backup via Clish), a Gateway does create (and in our case SCP) a backup regularly, but I did not come across a way to get informed when a backup schedule failed.
So it might be months until you realize, that even though you have had a successful backup-schedule in the past, that the most up to date backup is some months old.
Except checking clish "show backup status" (either by hand, cronjob or SNMP Extension) I do not see a way to alert the admin, that a backup failed.
Is there a possibility to monitor this, ideally via SNMP?
Our current setup is R80.20 - R80.40, but since the backup schedule did not really change I don't think this is version relevant.
