DPM 2019 slow backup performance

Question

We facing problem with DPM 2019 while running backup. Several backup jobs seems to hung. The average disk active time of the backup Disk is around 96%. But I can't figue out why there is so much traffic to the volume.

At this time sometimes after restart no jobs running?

Any ideas?
