I don't think you can have two devices classes (one with and one without
encryption) sharing the same pool of scratch volumes (one logical library)
using LTO hardware encryption.
This is because the volume label on the tape is either written encrypted or it
is not, I don't think the none
Hi,
Is anyone backing up exchange 2010?
If so, which tdp ver, and which tsm server ver are you using?

Hi Dave,
Microsoft Exchange Server 2010 changed some significant architectural
constructs.
It is not a simple change like Exchange 2003 -- Exchange 2007 was.
One thing to note is that Microsoft will NOT support legacy-style
(streaming)
backups with Exchange Server 2010. That means VSS backups
Currently there is no official TDP version available to the public.
Contact your IBM rep and ask about the limited availability TDP.
You will need to be running B/A client 6.1.3 for the TDP to work properly.

This is for TSM-managed encryption (the library is set to
application-managed).
You only need 1 set of scratch tapes.
One library, two storage pools, two devclasses, one encrypted, one not.
Same pool of scratch tapes.
When an encrypted tape goes scratch and comes back from the vault, it can be
Any compressed/ encrypted data will not de-dupe well or if at all.
(Compressed / Encrypted Data have unique signatures every time)
In regards to client side compression, that feature tends to be of value
on a small remote site or if you have a 10Mb lan. You can force the
client compression off

Go to the link in sig and do a search on

Hi Andy,
Thank you. The cause of those numbers is now clear.

Actually, the encryption isn't bad from a performance perspective. In our
testing, enabling encryption only incurred a 5-10% perfromance penalty.
The real issues come from the fact that encrypted data doesn't compress, so if
you encrypt on the client without using client compression, your tape
Well, generally speaking with any Dedup product you don't want the nodes
compressing the data. As we stand now, they don't, as the Tape Drive
Hardware compression is much better, and it's easier on the node's
processors, anyway. And, with a VTL/DL that does both, compression and

Just to chip in here.
We have 3 DDR's (2 at remote sites and one in a main DC) and are seeing
4.4:1 compression. That's with a reasonable mix of data and no client
side compression.
Whilst dedupe isn't superb, but as we know it's generally lower with TSM
anyway, a big advantage is DDR
There are certain data that should not be compress again by the client.
Files that are already compress. Any backups that are done by the
various TDP components.

The note Andy refers to (ie search idle wait 100) recommends using
accounting log records to get accurate information.
I agree fully. In building Servergraph, we tried many different ways to get
session information, and the only one that was consistently accurate was the
accounting log.
Hello,
We want to migrate our tsm 5.3.6 to new hardware with 5.5.3 installed.
I have SCSI tape library 3573 on old server (5.3.6)which we use as copy pool
only. We keep our primary pool on disks.
I installed everything on new server and I physically moved tape library to new
server. When I

I am trying to generate a BACKUPSET for a node that I´ve just executed a

Without an HBA you wont be able to acces your tape drives from the storage
agent.

We have been running TSM server 6.1.2.1 on AIX 6.1 for a couple of

Downloaded the 6.1.3 package, ran the upgrade procedure and lo and
behold, the performance problem was no better. At that time, I also
Hi Sam,
I have successful run a couple of upgrades from 6.1.0.0 to 6.1.3 and also from
6.1.2.1 to 6.1.3.
But I have only been upgrading on Linux Servers and not AIX.
