[In part 1 of this 2 part series, I gave a brief overview of alternatives to NDMP. In this post, I’m going to discuss in a bit more detail the advantages and disadvantages of each.]
Here’s a table of the advantages and disadvantages of alternatives to NDMP and NDMP itself.

Since I originally wrote this in response to a customer asking me what Unitrends does, the answer is that we support direct NAS attach. That way we support small NASs (such as the Drobo, NetGear Readynas, Iomega, Qnap, and other smaller NAS devices), entry level unified storage such as the EMC VNX/VNXe and NetApp FAS2000 series, all the way up to scale-out NAS from vendors such as EMC, NetApp, Dell, Nexsan, and others.
