+Backup and restore operations export several metrics using the expvars interface. These are available at the `/debug/vars` endpoint of Vtbackup's and VTTablet's http status pages. [More details can be found here](../../features/monitoring/#3-push-based-metrics-system).
+
+## Backup metrics
+
+#### backup_duration_seconds
+
+_backup_duration_seconds_ times the duration of a backup.
+
+## Restore metrics
+
+#### restore_duration_seconds
+
+_restore_duration_seconds_ times the duration of a restore.
+
+## Example
+**A snippet of vtbackup metrics after running it against the local example after creating the initial cluster**
+
+(Processed with `jq` for readability.)
