Backup Appliance 5230 for Scale out Storage

Hi everyone, I am going to work on the design of backup solution for scale out storage (700TB) with Backup Applince 5230.

The solution is based on NFS scan through the snapshot thus I am going to mount to daily snapshot and run the backup process through NFS.

The question is can I add several appliances to one master server and the Netbackup (master and catalog) will be a dispatcher for writing the data between several paaliences.

Thanks,

Boris
