Nick,
Tape library can be any standard SCSI or FC device (supported by
Networker). Sounds like your library will be fine,
The tier level does refer to NAS device
Yes, you will need a library license for the NAS attached library.
There are alternatives to using NDMP - NAS devices generally present
shares over a network. One method of backing up could be to have the
Network server (or a storage node, or another client of suitable OS)
connect to the network share and use save -L to backup the network
shared drive. It means that all of the data goes over the network (not
as big an issue these days) but it does mean that you don't have the
issue of NDMP tapes and non-NDMP tapes.
You could, if you wanted to, use NDMP and have it backed up via a proxy
storage node to a standard tape device and avoid NDMP devices this way.
Better still, employ a second NAS at another location and snap mirror
(or whatever flavour your NAS does) the volumes... but this takes us to
a totally different area...
Regards
Bob

Subject: [Networker] NDMP questions
Hi all,
I've been asked to look into possibly adding a NAS to our environment
and back it up using Networker. I've never used a NAS before so I have
some basic questions which I'm hoping someone will be able to answer for
me.
I've figured out that I'd use NDMP to back up the NAS device (at this
stage I'm not sure which NAS device we'd be getting). Looking through
the admin guide it looks like there are a few ways to configure this. I
think we'd be looking at the local backup, where we connect a tape
library directly to the NAS.
So my first question is, does the tape library have to be a special NDMP
aware library, or can any SCSI library which is supported by Networker
work? Specifically, we have a Quantum SuperLoader 3 with one DLT-S4
drive which we'd be looking to attach to the NAS.
My second question is to do with licensing. There are various Tier
level licenses for NDMP client connections based on the number of
processors. Am I correct in saying that this is the number of
processors in the NAS unit itself? And, is an autochanger license
required for the library which will be attached to the NAS?
Thanks,
Nick
