Re: Exchange 2010 backup performance

[Del Hoobler]

Hi Wanda,

I have a few ideas for you...

--

Are you running in a DAG environment? If so, you could do some
load balancing between DAG Servers:

Most of this in the Exchange book under "Managing Exchange Database
Availability Group members by using a single policy":


http://pic.dhe.ibm.com/infocenter/tsminfo/v6r4/index.jsp?topic=%2Fcom.ibm.itsm.mail.exc.doc%2Ft_dpfcm_bup_reduce_redundant_exc.html

The key to "load balance" when setting up the scheduled backup
script is to have a separate invocation of each database. For example:

TDPEXCC BACKUP DB1 FULL /MINIMUMBACKUPINTERVAL=720 /PREFERDAGPASSIVE
TDPEXCC BACKUP DB2 FULL /MINIMUMBACKUPINTERVAL=720 /PREFERDAGPASSIVE
TDPEXCC BACKUP DB3 FULL /MINIMUMBACKUPINTERVAL=720 /PREFERDAGPASSIVE
TDPEXCC BACKUP DB4 FULL /MINIMUMBACKUPINTERVAL=720 /PREFERDAGPASSIVE
TDPEXCC BACKUP DB5 FULL /MINIMUMBACKUPINTERVAL=720 /PREFERDAGPASSIVE

Then, run this command from each of the Exchange servers at or
about the same time.

Here are a few more things to look at:

To help with some performance issues, some customers have split
their backups into multiple "threads" or "processes" in two ways:

1. Increase the value of the RESOURCEUTILIZATION parameter in the
   DSM.OPT file for the DSMAGENT. Trying setting this to "10".
Important: This needs to the DSM.OPT file for the DSMAGENT
   not the DP/Exchange options file.

2. Split the backups into multiple parallel instances of the
   TDPEXCC backup execution.
 i.e. the create separate invocations of DP/Exchange that back
 up a different set of databases. For example:
 TDPEXCC BACKUP db1,db2,db3,db4 FULL
 TDPEXCC BACKUP db5,db6,db7,db8 FULL
 TDPEXCC BACKUP db9,db10,db11,db12 FULL
  Put these in separate command files and stagger the
  launching of them by 10 minutes or so.
  The key here is that you need to make sure that you don't
  have any LUNs that appears in more than one invocation.
  In other words, you don't want to snapshot the
  same LUN in separate invocations.

Note: The integrity check is a Microsoft tool. IBM has no control over
the speed of that tool. DP/Exchange invokes the Microsoft ESEUTIL program
to perform the integrity check. It's a very I/O intensive program that
must examine every page of the database file (.EDB) and all log files.

--

If none of these help, you should open a PMR to get the performance team
to look at your environment.



Thank you,

Del

Exchange 2010 backup performance

[Prather, Wanda]

Are Exchange 2010 VSS backups affected by TXNBYTELIMIT settings in the baclient 
dsm.opt?
Or is there anything else I can tweak to improve TSM throughput of a 2010 full 
backup?
Got a 10G network, but Exchange full backup performance not impressive.

Thanks for any ideas  - links to relevant doc also appreciated!

Wanda

How to move directories to different management class?

[Grigori Solonovitch]

I have domain with a few management classes. All directories are usually coming 
to MC with the longest expiry period.
I have added new MC with very long expiry period for some specific data and all 
directories from nodes without DIRMC in dsm.opt  immediately came to new MC.
I do not want to keep directories in new MC and added DIRMC into dsm.opt on all 
nodes, but I still can see directories in new MC.
How to move directories from one MC to other?
Thank you very much in advance.

TSM 7.1 Silent install

[Hans Christian Riksheim]

I can not get silent install to work. with the 7.1 BA client for Windows.

When I look into the information center for 7.1, the procedure is exactly
the same as for version 6 although the paths after unpacking the 7.1 client
is vastly different from unpacking version 6.

Is the procedure in the information center correct or is it just copied and
pasted from previous versions?
