You're quite right, Rui.

I'm investigating a solid Enterprise Backup/Restore implementation within a 
divers network environment, where all (LAN) networks are divided/protected by 
firewalls. In what way can I suggest to implement for instance a Network 
Storage Manager, while the traffic between the networks already is problematic?
The possibility to connect multiple ADSM servers with each other looks nice, 
but is still costly and they all need to be managed. 
Therefore: please IBM, develop one central ADSM server with a build-in 
distributed backup possibility!
Does anyone know how I can solve my network traffic problem?
