Netezza backup with backup exec 2013/14 ?

good evening, I'm trying to integrate Netezza with backup exec I'm not familiar with backup exec so I need some hints :

I gues I must install backup exec agent for Linux on my Netezza box ? (Netezza is running RHEL 6.x)

As I don't have any local storage on my NZ box for a Database Backup can I run something like

>nzbackup <options>|<backup exec agent> ? to avoid to land my full backup file on the netezza box or on nfs drive ?

Any link for examples how to backup linux files using backup exec would be more than welcome

Thanks in advance
