Can anyone explain the expected behavior in the case where you have a
server with 4 interfaces, and several clients with 1 interface each,
all on the same switched network?

backup1-a    192.168.1.11/24
backup1-b    192.168.1.12/24
backup1-c    192.168.1.13/24
backup1-d    192.168.1.14/24

client-1     192.168.1.16
client-2     192.168.1.17
client-3     192.168.1.18
client-4     192.168.1.19

Can Netbackup balance the load across all the interfaces?

Is there any way to increase throughput over a certain segment by
using more interfaces, but NOT using trunking or bonding?
