Yes and no : AFD are NOT like tape : When 1 is full, the Session
is suspended until AFD space is recovered and does NOT continue
to another dev even if it is labelled in same pool.
So, best is to create 2 AFDs, in 2 separate pools. Do load balancing
of your backups, some to AFD1's pool, the others to AFD2's pool.
I have 6 AFDs devices defined as E:\AFD, F:\AFD, G:\AFD,
H:\AFD, I:\AFD and J:\AFD each one labelled in its own pool and I do
load balancing of my backups using groups. (define groups in AFD pool
authorized group list)
Works like a charm. E and F are 2TB Luns I stage in parallel.
Then stage as you need. Do not forget, 1 read (recover/stage/clone)
operation a time per device :-)

Subject: [Networker] How to use multiple AFTD devices
I have a question. I have a Windows NW 7.4.2 storage node that I use as an
AFTD device. The disk space in question is presented from my SAN. So I
define the device as "FQDN:drive letter\file path", and this all works
wonderfully - I back up to disk, then clone to tape.
Problem: I need enough space to total 2.5 TB in size, and my SAN only
allows me to present at most a 2 TB disk (it's an HP EVA 8000). So what I
was thinking - present 2 disks on 1.2TB each (the daily backup size is 1.1
TB, so 2 drives would allow me to keep 2 days backup on disk).
What kind of config do I need to tell NetWorker? Do I just define 2
devices, and as long as they are both in the same media pool, things will
Just Work? Will NetWorker treat it the same way it treats tapes - i.e.,
will it fill up drive X: first, then start using drive Y:? Will it use
parallelism, and write to X: and Y: at the same time? I'm guessing that I
can define multiple AFTDs this way, right?
Has anyone done this? Is there something I am not taking into account?
Thanks
