Dedicated Veeam Backup network in VCF8+

Post by Lopese »

Hello
I am designing a dedicated back-up network to include two different vsphere clusters existing on the same management LAN.

My goal is to route all backup traffic through a dedicated network.
How to i achieve this goal?

Esxi hosts have default host managent vmkernal1 (172.30.80.0/24)

Do I create a separate vmkernal2, with service as management for each esxi host in (10.50.10.0/25).
Create Veeam proxy server with nic in same subnet as vmk2.
Create a static route pointing traffic in (10.50.10.0/25) through veeam proxy VM, join veeam management server with backup lan network ip for hosts (10.50.10.0/25).?

Thank you.

Hello, Eddie,

Deploy one proxy VM per cluster that leverages the HotAdd backup method; this is the recommended option. Give each proxy two vNICs: one on the management LAN (so VBR can task it and reach vCenter), one on 10.50.10.0/25 (the backup VLAN). Each host in the cluster already has a second VMKernel in that same subnet with the Management service enabled. And VMDK reads should then happen internally via hot-add.

On the repository side, give the repo (or you may use a single repository gateway for the repositories for example) server a NIC in 10.50.10.0/25 as well.
Add 10.50.10.0/25 as a Preferred Network in VBR.
Specifying Preferred Networks

That's what forces the proxy>repo data stream onto the backup VLAN.
Without a repo-side NIC on that subnet, Veeam Backup & Replication has nowhere to route it and it will fall back to management network.
If that implementation doesn't work for some reason, I'd recommend you to open a case with Veeam Technical support on that matter, who can analyze the setup with the logs.

Thank you very much. This was exactly what I needed fir guidance. I will report back once implementation has completed successfully.

Hello,
I read this thread and am fully interested in it :)
As I am trying to design something really close, too.

Purpose is the same for me : to have a dedicated backup network.
My environment is a brand new Veeam 13 + one main vSphere cluster in v8u3i, and other existing clusters in v7u3.

I wonder, in order to get a dedicated vlan for backup...
On which machine would it be better to put a dual network? here Vladimir you put it on Proxies.
I explain.
Lets say my production vlan ID is 100, and my new backup vlan is 500.
My ESX and vCenter servers are in 100.
I first plan to add a new vmk to each ESX in 500 (no need to enable management on it IMHO ; either tick nothing in VMware on that vmk, or maybe NFC ?).

So I could do as you say here, Vladimir.
1. And will have every proxies with a vnic in vlan 100 and another vnic in 500.
2. Or I could do that on my Veeam server, and have all proxies in 500 only.
3. Or I could do that on vCenter server, and have all my veeam machines (server, proxies, repo) in vlan 500 only.
4. Or, I am not network expert, but I could do level 3 routing I suppose, maybe between Veeam and vCenter?

What do you think would be the best please ? I think mostly in terms of security, but maybe elsewhere. Performane would not change I think.

And could I put 2 vnic on the Veeam server appliance in v13 nowadays ?

Any opinion will matter to me :)
