Ed, Rusty,
Have you noticed if the load on the DNS servers has gone down? I
remember building an HPUX master server with thousands of clients. Our
master server hammered the DNS server. We ended up configuring a DNS
caching server on our own master. It didn't add a lot to the load on the
On an sidebar question, we are also planning on implementing Linux
servers, but with VxVM and VxFS. Has anyone compared the relative
performance of VxFS versus EXT3?

It is delployed with 6.5.6, but can be used with 6.5.5. There is an

Nate,
Any filesystem you have will start out quickly but then drop in speed
as it starts drilling down into the directory structure. The more
directory levels you have, the slower it is. Which makes sense, since you
are sort of following a tree structure down to the lower directory levels.
Nate,
It is possible. I currently have OpsCenter (Windows 2008 64 bit)
monitoring 6.5 Master servers. However, it does involve installing 6.5
media server in order to use the media server binaries to communicate with
the master. I had Support help me in the install, I don't think I could
Agreed.
Also, be aware that you will typically not be able to stream data to a
disk array as fast as you can to tape drives. (Assuming LTO3 or 4 type
performance.) Unless you have a pretty beefy disk array with your RAID
configured for streaming. The nice part is that since it is disk, small
Wayne,
I'm assuming you are using the DD as VTL, not using OST. If so, yes,
using SSO you can share the VTL drives with the other media server. I
believe you have to have the SSO license on all media servers that share
the drives. It used to be sold on a per drive basis, not sure how they
What I have done in the past is downed the drives I want to use with
tar. You can then use robtest to move tapes in and out of the drives. You
have to be careful with your mt and tar commands so as to not unload
the tape. If you unload the tape, you will have to use robtest to move
that tape
Don,
It entirely depends on your priorities.
If you can't afford the cost of the agent, well, that's one way to do
it. Although you better be figuring in the total ownership cost of 3X the
disk space of having your live db and 2 backup copies online. That is not
cheap either.

Hi all,
I'm getting prepared to deploy an EMC DL3D 3000 VTL with NetBackup
6.5.3.1. We also want to run NDMP backups to the VTL from NetApp filers. I
can't find any matrix that shows that this combination is supported - from
NetApp, EMC or Symantec. Or any documentation that tells you to run
I've often wondered about requesting an enhancement for a NetBackup
option - Expire with prejudice - just for these situations. Something
you could set on a global, pool or retention level basis...
Greetings,
I am pretty sure that a lot of you who are working for big enterprises are
aware
When Symantec first changed their support site I complained too.
Since I was with a small company, my input fell on deaf ears.
In addition, I now have to support Storage Foundation. Try to get
patches for Storage Foundation!!! Go search VxFS patches, filter out
various versions and

Of course, if you don't have one of those available...

You can have it fast, cheap, reliable - pick any two.
That's doing exactly what Randy wanted not to do: specifying specific
days in a schedule. That means you will, eventually, have to go
Adam, all,
If your NTFS volume is over 80% full, the performance starts to
degrade. I've tested this and verified that it does happen. I didn't do
enough testing with controls to truly characterize performance, but it
can be demonstrated. At 85% full, you will notice a significant

restores are not an issue. At most, even with 20GB fragments like Ed
uses, you may spend an extra minute or two pulling the file off the tape.
