Updated a two node XCP-ng 8.0 homelab without any issues

I wonder if the backup (and restore) traffic is going through XO (on the management network) or does XO advise the xcp-ng host where the backup remote store (on the storage network) is, so that the traffic stays on the storage network? Read some articles on the XO forum and the internet, but did not get a clear picture on the recommended architecture.
