Backup Metrics

A chart of backup metrics over time is shown on both the dashboard (table view) and the server details page.

  • Dashboard, the chart shows the total number of backups recorded in the duplistatus database. If you use the Cards layout, you can select a server to see its consolidated metrics (when side panel is showing metrics).
  • Server Details page, the chart shows metrics for the selected server (for all its backups) or for a single, specific backup.

Backup Metrics

Inline Chart Controls​

Quick access controls are available directly on chart panel headers for easy configuration without navigating to Display Settings:

Time Range Selector​

Pill buttons appear in the chart header for quick time range selection: 1W | 2W | 1M | 3M

  • 1W: Last 7 days (rolling window)
  • 2W: Last 14 days (rolling window)
  • 1M: Last 30 days (rolling window, default)
  • 3M: Last 90 days (rolling window)

Changes made here sync with your Display Settings, so your preference is remembered across page refreshes.

Chart Style Toggle​

A toggle button in the chart header allows you to switch between:

  • Smooth Lines: Display data points connected with smooth curves
  • Bar Chart: Display data as discrete bars for each time period

Both modes use time-bucket aggregation for optimal display. Empty periods in bar mode render no bar. Your preference persists across page refreshes and is synced with Display Settings.

Chart Data Consolidation​

When multiple backups occur on the same day, duplistatus consolidates the data before displaying it on charts:

  • SUM: Used for cumulative metrics (Duration, File Count, File Size, Uploaded Size)
  • LAST: Used for Storage Size (the most recent value of the day)
  • MAX: Used for Available Versions (the highest count of the day)

This consolidation happens before time bucketing is applied, ensuring accurate aggregated metrics. For example, two backups on 5/12/26 will produce one consolidated data point on the chart.

Metric Definitions​

  • Uploaded Size: Total amount of data uploaded/transmitted during backups from Duplicati server to the destination (local storage, FTP, cloud provider, ...) per day.
  • Duration: The total duration of all backups received per day in HH:MM.
  • File Count: The sum of the file count counter received for all backups per day.
  • File Size: The sum of the file size reported by Duplicati server for all backups received per day.
  • Storage Size: The sum of the storage size used on the backup destination reported by the Duplicati server per day.
  • Available Versions: The sum of all available versions for all backups per day.
note

You can use the Display Settings control to configure the time range for the chart.
