The server initially tries to contact nsrexec on the client.  This
client then reports the hostname, and the server attempts to verify that
the name the client reports is on the access or alias list for the
instance.

If that succeeds, the client is passed a request for a backup.  The
backup may contain an optional 'server network interface'.  If present,
the client will attempt to send data to that address.  If not present,
it will just resolve the default name of the server.  The routing table
on the client will pick a local interface based on routing to the
correct server address.

> Are both used?

Only if you have some sort of trunking or load sharing software running
on the client.  Or if you have two savesets running simultanously
(client parallelism >1) and each specifies a different server network
interface, and the routing table on the client uses separate local
interfaces for routing to them.

If the interfaces on the client are to the same subnet, you'd probably
want to make this happen through load-sharing configurations, not
through networker directly.

> Is it possible that different NICs are used for each save-set?

In some situations, yes.
