As the subject, can I submit a feature request to have the option to chose dedicated management network for VBR as well as dedicated data networks. This is on the back of case 02008794 which has the details for why and also this forum post veeam-backup-replication-f2/slow-job-initialisation-since-moving-to-9-5-t39741.html
In a nutshell, if choosing a preferred network in Veeam, it would seem that it tries to use this network for management and data transfer. The issue is if the data network connected to Veeam proxies is not routable to the Veeam management server, job initialisation takes a long time to start as the proxy servers try to communicate with the management server over the preferred network before failing over to other available subnets connected to the proxy servers. Windows network binding order does not resolve this issue and is not an available option in server 2016.
