[Networker] Some comments on NetWorker 7.4
2007-08-24 10:16:55
I installed NetWorker 7.4 on a Dell PowerEdge 2950 with three dual-
channel HBA cards and a 1GB network drop. The 2950 is running Red
Hat Linux AS 4. The Linux box is connected to a Qualstar TLS-88132
with fibre channel LTO-3 tape drives, all of which are connected to
the Dell server. Nothing fancy is being done in terms of device or
library sharing. This set-up is not yet in production so I am running
on the default evaluation license.
I am coming from a NetWorker 7.2.1 perspective, which I run in
production on entirely different hardware. I have been testing
NetWorker 7.4 to back up my MacPro workstation with the 7.3.3 client
and another Linux box with the 7.4 client that holds 1TB of data,
which is also not yet in production.
My plan is to try our NetWorker 7.4 for a month, then wipe it out on
this Linux box, install 7.4 on my production Solaris 9 server, and
make this Linux box a 7.4 Storage Node.
So anyway, I really like the new GUI! Its far better than the old
green X Motif GUI and a lot more flexible. I deleted and reinstalled
the tape library resource and clients a few times, just for the
practice of it, and the new NMC GUI makes the process so easy.
Can I recover data? I am still testing that aspect of 7.4, but as I
write this, I am recovering 1TB of data that I backed up from my test
Linux box last night. I also did that backup using NetWorker 7.4's
AES encryption ASM, but I am not sure if the data really was
encrypted or not. The details for that backup don't show any errors.
I have already tested recovering data from my Mac and it worked fine
(even though NSR reports a reverse DNS problem each time I back up my
Mac).
I still have a lot to learn about 7.4, especially its reporting
feature. One thing I haven't figure out yet is the nwrecover GUI,
like how to start it. When I type "nwrecover" on the Linux box, I get
an error that says "125:nwrecover: unable to execute with hard links
to binary /usr/bin/nwrecover" and the NetWorker 7.4 Administration
Guide sheds no light on it, although the CLI recover works fine. If
anyone has any idea on how to fix that problem or if you have any
questions about my experience running 7.4, let me know.
One thing I can't test well is save group email reports because we do
not have a sendmail agent running on this PowerEdge 2950, and I do
not intend to run sendmail there.
