Tracing/debugging: "restore from snapshot"

Hi,
I have read: https://www.home-assistant.io/integrations/logger/, but I can’t figure out how to track/trace/debug hass.io when it takes a snapshot or when it reverts to snapshot.
In my configuration.yaml, I have

logger:
  default: error

If I set it to:

logger:
  default: debug

I get too much noise (cameras sending a frame every second)
So, bottom line, does anyone know how I can enable more detailed logging on the snapshot process only?
thanks,
