Run backups through specific NIC

Thread needs solution

I have two NICs configured in vmProtect. One is on a private vswitch with a gigabit connection.

I would like to run backups on this network only so that it's faster.

Is there a way to prioritise what NICs are used to backup the VMs?

Here is some more information about my vmware networking.

Each of my hosts has a private gigabit NIC which I want to use to do backups on.

If you look at vm_network06.png you can see this is the host I have the Acronis Appliance on. The appliance has 2 NICS, one is on vSwitch0 and the other is on vSwitch1.

If you look at vm_network07.png you can see this is the host I have the VM (test) that I want to backup. test is only connected to vSwitch1.

I am guessing that since the Appliance uses the management network that perhaps I should change the network configuration so that both NICs are on the vSwitch0. If I do that then I'm not sure how vmProtect will prioritise traffic so that it only goes over the gigabit NIC?

Hi!

The management network is used by appliance to perform Run VM from Backup operations and also for management traffic between the host and the appliance (getting infrastructure details, list of VMs, disks, etc.). You can ensure that the traffic goes through specific interface via 'route add' command executed from appliance console (to switch to console go to Appliance GUI, then press Ctrl+Shift+Alt+Space+F1, then Alt+F2). Please check the examples at http://www.cyberciti.biz/faq/linux-route-add/ .

In case you have different IP addresses for your networks, for example 192.168.x.x and 10.0.x.x then it is sufficient to define the backup location via IP address, i.e. \\10.0.x.x\share and there is no need to define the routes manually. The traffic will go through the interface connected to 10.0.x.x network (regardless of gateway settings, if you address the same subnet of course).

To verify you can check the performance tab of the appliance in vSphere client -> check the network interfaces activity.

Thank you.
