We currently backup exclusively to our 2 dd400.  We have one for the OS's and 
one for oracle backups.  Works great.  I have it configured to use the NFS 
mount as an adv_file device.  Actually, we have each pool having its own 
adv_file device so that cloning doesn't effect recover.  Networker only 
allows one clone for the RO device and it also "appears" to block the device 
for recoveries during the clone.
