NW 7.5.2, Windows 2003 (server and client)
I know I will phrase this wrong, or use a technical term wrong, so I'll
just describe what I want, and then someone can tell me what it's properly
called, and (hopefully) how to do it.
I run a backup job that backs up MS SQL databases on one client. This
client is an AFTD storage node. So the job backs up to disk (fiber
connected SAN storage), and then clones onto a fiber connected library
(library connected to my NW server, not the storage node). Problem is, I
have about 1.7TB of DBs to back up, and my DBAs tell me they can't get rid
of any of them, and that - in fact - they might have more DBs soon, what
with the upcoming projects.
The problem I have is time, of course. It takes a long while to save to
disk, and even longer to clone to tape. And I have to run this job every
night, I'm told - no backing up only on the weekends, when I have a longer
backup time window.
So what I am wondering - what can I do to speed up this job? I don't think
I will be able to put a tape library/jukebox on this client, so I am stuck
using my existing library (an Overland 8 drive, LTO-4 fiber connected
library).
Are there any settings I can tweak to speed this up? Savegrp parallelism
won't help, since there's only 1 client running in this job. Server
parallelism is set at 32 (which is probably a bit high, anyway).
Client saveset definition is just "MSSQL:", since I don't know the names
of the specific DBs to list them, and the DBAs have a tendency to just add
new ones that I don't know about.
Suggestions? Where else to look? Some way to have it clone onto more than
1 tape at a time (is that "multiplexing")? To write out the cloned
savesets to multiple tapes at the same time, I mean, not to duplicate the
same savesets to more than 1 tape.
Thanks for any help.
