Hyper-V Appaware backup across VLANS

Post by Longclaw » Sep 20, 2018 6:05 pm

We have been using Veeam with VMware for a while, and have had no issues with Application Aware backups to windows server guest machines.

We have setup several new Windows Server 2016 Core Hyper-V hosts in a failover cluster. Our VeeamBackup server is on one VLAN, it has no issues backing up with Application Aware on the same VLAN. But when trying to backup systems from a separate VLAN, the application aware aspect of the backup is failing.

What is the best & most secure method for getting successful backups in this scenario? Looking for someone who has had experience with the same scenario.

Hi Longclaw,
I am assuming that both VLAN's are not capable of reaching each other. Is that correct?

I also assume now that you are using network connection to do the application aware processing. Question: Is the PowerShell direct method of doing app-aware processing working? What are you seeing in the log after the failed backup?

You can use two methods, both requiring something that connect the two vlan.

A firewall (tata can be a VM with your choice of firewall software) or a VM with a NICin both VLAN acting a guest integration proxy.

As best/most secure probably the first, but it require routing/networking modification, but the second, if correctly configured (firewall, network services on vm etc etc) can be effective.

NB:while the guest integration is a "small" network load, test the scenario of restore, especially for file level and application restore...
