Veeam Backup - Hyper-V alternative to VMkernel adapter

I’m new to Hyper-V and I’m wondering about the best way to setup our Backup infrastructure with Veeam Backup and Replication.

So far, we were using VMware. Our setup usually looked like this:

- ESX Hosts and vCenter are in a Management VLAN/Subnet

- Backupserver is in Backup VLAN/Subnet

- ESX Hosts have an additional VMkernel Adapter with an IP address within the Backup VLAN/Subnet

- Backup Server has entries in its Host file, pointing the hostnames of the ESX hosts to their IP address in the Backup subnet 

That way, restore operations are not routed and go directly over layer 2. How would a comparable setup look in Hyper-V?

You can tell veeam which networks to use In its config. Backup traffic will only go down those legs

Problem solved job done

I’ve done many deployments and it always works

you can do the same with hyper-v

in my old DC we had a backup vlan, the clusters and blades all had adapters on the backup vlan (technically was physically separated too)

all the veeam/dpm traffic went across those adapters

I’m curious about other folks practice here as well, though I’m on Rubrik vs Veeam. 

I opted to dedicate a pair of 25 gig interfaces to backup/live-migration. The team is managed by network atc with the management option so it creates a vNIC that I can assign to the backup subnet. 

The main difference seems to be that vsphere allows you to add the host via its regular name, but return the ip of the backup vmkernel port. For hyper-v I added the hosts via the dns name associated to the backup ip for each host. This has thus far worked fine to isolate backup traffic away from my primary team which cares management and VM traffic.

Also moving from vSphere to Hyper-V, we have the Veeam server in the mgmt network and have a separate storage VLAN.

HyperV emulates more of the network stack than VMWare ever did. So no "unlimited" bandwidth of the VMXNet3 anymore. Otherwise everything is pretty much the same.

Multihoming the hosts kinda defeats the idea of security zones, because the host becomes a bridge. But if configured correctly is perfectly fine tho. Way faster. Make sure the backup vlan hasnt set a gateway.
