Why copy the data twice or more? NFS-mount a directory on the DataDomain (should be geographically isolated from your production server) at /opt/zimbra/backup. You shouldn't use NFS for live data, but for backup I believe it's ok.
To get storage diversity, mount different hardware (local disk, iscsi, fc...) on /opt/zimbra/backup on alternate days, and double up the zmbackup -del line in crontab so that it will trim both backup sets.
I would keep doing /opt/zimbra/conf, /, /var/log, etc. with NetBackup, but especially if your target is DataDomain disk, I see no point in copying /opt/zimbra/(store,db/data,index,backup) again. Zimbra's own d2d backup does a better job.
