About Anomaly Detection

Last published : Apr 02, 2026
The Anomaly Detection feature monitors backup job parameters and then detects and reports anomalies for the backup job. No anomalies are detected until a minimum of 30 runs are completed for a backup job.
The feature also allows you ignore patterns that help to reduce detection of records that are not anomalies. In such a scenario, when the job runs again, that pattern is not detected as an anomaly.
The following backup job parameter, attributes, features, and so on are verified during anomaly detection:
  • Backup image size
  • Backup Item count
  • Deduplication Ratio
  • Backup Time
  • Data transferred
From the Backup Exec user interface, your can see the anomalies for the last 30 days. You can filter anomalies for the past 7 days, 15 days, or 30 days.
After the anomalies are detected, a score is calculated, based on which the anomalies are categorized as low severity, medium severity and high severity. You can manage the anomalies by confirming that a record is an anomaly or confirming that the record is not an anomaly.
You can disable this feature from the Backup Exec settings. After it is disabled, Backup Exec stops detecting any anomalies.
You can also generate the Anomaly Detection Summary report to view the details of the anomalies for the backup jobs.
