Can I expect the backups to use the Fibre Channel link in this scenario?

Hi,

We're evaluating a backup scenario using Backup Exec 2012 for a client and we'd like to make sure it's using the intended path. In this scenario, we'd like the backups to use the Fibre Channel link instead of the LAN link.

What kind of configuration would I expect to make in Backup Exec 2012 to make this work?

I've attached the schematic.

Thanks in advance,
