If you are looking to do offsite replication of your Netbackup data only, they
you should look at backup appliances, and the use of OST. OST and an appliance
from a vendor (DataDomain, Greenbytes, etc.) that supports it, can really
simplify your backup replication and recovery.

Hi Jeff.
Although I have a CX4-120 (yes it's a EMC CLARiiON) I will not replicate the
data using a storage feature. I want to use the Netbackup to do that
replication. That's why I won't use a appliance like the Data Domain.

Best architecture for deduplication with NetBackup
We haven't used the NBU native deduplication yet so can't advise on
that. However, your comment about not needing dedupe appliances yet
and the mention of CX4-120 (I'm assuming this is a Clariion array from
EMC) made me want respond.
Dedupe appliances (at least the ones from Data Domain[now EMC]) allow
for replication between sites. Since there are different sized DD units
it might even be possible to have smaller ones at the remote locations
all replicating to a larger one in your central location. You'd have
to check with them on that.
Clariions are good for holding lots of storage but aren't incredibly
fast unless you're using the fibre drives rather than the ATA ones.
Their SANCopy software has limits that made us decide we couldn't use it
when we were migrating a couple of years back. I doubt it has changed
that much. You want to look into its capabilities before planning on
using it for replicating to a central location.
