you can not restore a netapp ndmp backup to am emc filler

NDMP also has limitations, though.  The main limitation being that it does not support cross-filer recovery.  You cannot back up a NetApp and restore it to a BlueArc filer -- even though both support NDMP.  This is because NDMP is a communication protocol only; it does not specify the backup format.  Each filer vendor therefore creates their own format, making NDMP restores between filer vendors not possible.
