Job Activity > Variance > Backup Duration Variance report
This report provides an indication of how backup time varies from the average backup time. You can detect any anomalies if the variation is too high.
This report calculates the backup time variation of the last good backup with the average backup time per client, policy, and schedule type. If any variation calculation is greater than the selected value of variance when the report is run, the client, policy, and schedule type combination is shown with the actual variation.
