Hi guys,
I am setting up Veeam to backup my ESX server. I have a QNAP NAS device and everything is connected via a Juniper switch.

In Veaam, i can setup to backup via UNC path or with iSCSI. My nas supports both.

Is there any benefit of using iSCSI over UNC network path?

Speed! iSCSI should perform better in ideal situations.
Might take you a few more minutes to setup the iSCSI but it's worth the performance.

You should setup iscsi, especially if it has multiple nics and you can create an additional subnet specifically for iscsi traffic.  Enabling jumbo frames would increase performance as most of the traffic will be sequential.
