Netbackup and deduplication of VM's

I am thinking of moving to Netbackup from a Backup Exec environment and I'm not sure I understand the Deduplication process of VM server in Netbackup.  In BAckup Exec I select the VM server  and I am doing a snapshot backup of the VMDK files.  If I do a full backup of a VM in Netbackup with Client-Side Dedup enabled does it still do a snapshot backup or does it backup each individual file so when it does my next full backup it only backs up the chnages.  Most of these VM's are App servers with a few file servers mixed in.

If you do an image based backup, it will be deduplicated by the media server.  Just like BackupExec would do if you had Deduplication licensed.

If you do a client backup using an agent, then you can select client-based deduplication.

The process of backing up VM's and where dedupe happens is the same between BE and NBU.  It's just that GUI for NBU is ugly as hell, not to mention archaic.  Maybe 7.6 will offer a dressup/redesign.
