+#  Notifications only on failed jobs
+
+This is an example snippet based on the support article that explains how to do it in the AWS console
+
+[How can I get notifications for AWS Backup jobs that failed?](https://aws.amazon.com/es/premiumsupport/knowledge-center/aws-backup-failed-job-notification/)
+
+
+
+```hcl
+module "backup" {
+  source = "lgallard/backup/aws"
+
+  [...]
+
+  # Only notify on failed jobs.
+  # https://aws.amazon.com/es/premiumsupport/knowledge-center/aws-backup-failed-job-notification/
+  notifications = {
+    sns_topic_arn = aws_sns_topic.backup_vault_notifications.arn,
+    backup_vault_events = ["BACKUP_JOB_COMPLETED"]
+  }
+}
+
+resource "aws_sns_topic" "backup_vault_notifications" {
+  name = "backup_notifications"
+}
+
+resource "aws_sns_topic_subscription" "devops_subscription" {
+  endpoint = var.backup_notification_address
+  protocol = "email-json"
+  topic_arn = aws_sns_topic.backup_vault_notifications.arn
+  filter_policy = jsonencode(
+    {
+      "State" = [
+        {
+          "anything-but" = "COMPLETED"
+        }
+      ]
+    }
+  )
+}
