@Tony Santos Thank you for reaching out to us!
In the default backup alerts solution, only alerts for failed backups are sent (not successful backups). To configure alerts for successful backups, you could either use custom log alerts (https://learn.microsoft.com/azure/backup/backup-azure-monitoring-use-azuremonitor) or our newly released metric alerts solution (https://learn.microsoft.com/azure/backup/metrics-overview)
You can also refer to this doc (https://learn.microsoft.com/azure/backup/monitoring-and-alerts-overview) which gives an overview of the various monitoring and reporting options with regards to Azure Backup.
