Yes , with single network adapter.

We using segmented network layout 
aka own network-interface for production, management and backup
so bandwidth is not a problem for copying.

Cause server are also configured own VLANs and firewalls between
segments blocking traffic and eating performance so remote-remote
rsync sounds good and gives more ways to copying data easily to
server to server example in hardware refreshing cases.
