Yes, in this case to get file based backups you need to have the client run some backup software.

I haven't played with this myself, but don't see any reason why it wouldn't work (feel free to pipe up if anyone sees any problems with it) - you could probably use OSSV (Open Systems Snap Vault) on the client (ie: inside the lun) and still use the netapp as a destination.
