Netvault & VMware best practices

Hi Community,

I'm curious to know how do you plan your VMware backup on NetVault. I'm wondering if we are using the good plan, i explain : 

Each week-end we do a full backup then each day a differential backup. I'm searching to reduce the backup time of my full, for example maybe some of you are doing only one full backup at initialisation ? i have never test that.

Regards,

Ben
