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.
