Struggled though a barren period of no filers................but
I'm about to get an F760! I've used these before, but this will be new to this company. At the same time we are considering a backup solution. Actually that's one of the main reasons I was able to get the filer in - snapshots and all that good stuff.
The standard for our associated companies is Legato Networker.
I've read through the threads from early last year - NDMP not yet, ACL's only via NT etc. etc.
So, what is the latest? Would appreciate opinions on the following:-
If I want to preserve NTFS permissions then should the Legato server be on NT?
If so, Is Legato reliable/stable on NT? If it works and is a lot cheaper then OK, with have the people to run either.
For information, will will be at ~ 750 G, probably 2/3 rds NT data, the rest an eclectic variety of unix(s) and linux.
Thanks in advance for all input.

Only a client needs to run on an NT. There is also the NetApp client which isn't Legato's best work and may not work with the latest DOT.

I can attest to this. :)
Currently, the Legato ClientPak for Netapps is "in a primitive stage" (the words from Legato engineer, not mine), and is a big resource hog. If you are running your filer with moderate load, the ClientPak is going to take a lot of CPU cycles. I've noticed a couple of our filers will be running at 100% utilisation sustained when the ClientPak is working.
I hope that future releases of the ClientPak and upgrades to ONTAP will take into account process priority or put some sort of control on resource allocation for the software. It's got to run such that it doesn't adversly affect load and performance too much on the filer.
Of course, saying all that, I really hope that Legato and Netapp will keep their ONTAP and ClientPak development and updates in syn with eachother. It's bad enough having to upgrade the ONTAP every few months, but then having to get patches for Legato for every new release is ridiculous.
The ClientPak works well, and does improve the time it takes to get data backed up, but more work needs to be done on how the operating system and the java subsystem runs the ClientPak.

That's a whole other can of worms... :)
I had a filer crash due to some rsh bug, according to the core dump analysis from Netapp. It happened when the ClientPak was running. While there is no apparent evidence that the ClientPak was the cause of the crash, I'm suspicious. I guess I will need deeper technical info on how the ClientPak operates on the filer.
Legato server I think is a bit tempermental, as I get a server crash one a month or so, and I'm sure it's Legato. Perhaps something with the kernel and Legato is to blame.
