Greg,

I will take a crack at answering this for you as a "guy in the know..".

First things first; you are not the first to bring this up. As you may or may not know, NetApp wrote a protocol several years ago called NDMP which stands for Network Data Management Protocol, which allows for a "standard" that controls remote tape devices, storage pools, etc. Most every backup vendor signed on to support the protocol (Veritas, Intelliguard, BudTool, Seagate, CommVault, etc.) except Legato, who maintained the "superiority" of their proprietary system. There have been a large number of VERY big NetApp installs that have been pushing Legato to provide native NetApp or they would switch to another product.

This led to the co-development of a Java-based Legato Networker client that will run directly on the Filer. The expected shipping date of this product is Q2/99. This product will be distributed, supported (and presumably sold) directly by Legato.

But wait!! Things get EVEN better! On 1/28/99, Legato announced that they were acquiring Intelliguard Software:

One of the main reasons cited for buying Intelliguard was the NDMP technology.

EVEN BETTER!!!!!!!!! On 2/2/99, Legato announced that all Networker products will be NDMP compliant in Q3/99:

With a big sigh of relief and a smile on their faces, NetApp customers and employees could give a hearty YAHOO!!!

Now, the question was asked about keeping the CIFS attributes during backup; both of the methods above will allow this to happen. In current environments, backups need to be done by an NT machine running Networker, OR having a UNIX Networker server that backs up an NT machine with the Filer mounted on it.

I hope that this helps.

Dear Toasters,

This is along the lines of the "Future Newbie" thread, though I'm not new to NetApp boxes. I am looking to get our first here at this company. We use Legato Networker to backup our Engineering systems, which I support. (We use HP's Omniback and a StorageTek tape library for our business systems, but that's another post....) The problem is, I'm not clear on how I'll backup an F740 (~180 GB) using Networker.

I've read the "How to Integrate..." white paper on the NetApp site. I've read the ancient "Backing Up NetApp..." on the Legato site. Neither of those seem to address our situation: Networker server running on Solaris; NetApp server with NFS and CIFS. How do I? I can connect a Quantum DLT stacker to the NetApp, but can I make Legato use it? If not, how do I backup over the network, given that I want to preserve NT ACLs? The "How to Integrate..." document shows how to do this when Networker runs on an NT machine, but we have it on UNIX.

I'm looking for a definitive answer, on the order of, "We do it here and it works great!" (along with the how-to, of course). I'm bucking the prevailing winds in trying to bring in a NetApp. Tiny issues like, "No proven way to back it up," could result in me supporting a new HP or Sun server. (Not that I don't use their equipment already, but the combination of RAID and NFS+CIFS is too much complexity on UNIX servers, IMHO.) All help is appreciated.

Greg
