Trying to restore Exchange database to a recovery group on same server.
The restore runs but is s slow it's not practical; 100 GB database
would take over 8 days.
Neither IBM nor Exchange experts can figure why it restores so slow.
Have checked parameters, etc.

Orin,
When you say the IBM experts cannot figure this out,
I assume you meant you have a PMR open with TSM support.
Is that correct? If not, please open a PMR so that the
TSM performance team can figure out where the bottle-neck is.
If so, I would continue to drive the PMR with IBM support.
Orin,
There is a bug in the early 5.3 client API where the diskbuffsize
parameter had a bad default causing slow restore times. Try setting
diskbuffsize 32 explicitly in your opt file.
I couldn't find the apar again when I just went looking for it, but I
did use this fix on some Windows
Orin,
I can confirm, what Bill has already told you, from first-hand
experience using TDP for Exchange in W2K3 environment that it works
flawlessly.
You do not need to setup another temp. box to do that, this is the main
purpose of RSG in W2K3! You do not need to dismount any production
stores
The purpose of the Recovery Storage Group was to allow for this restore to
happen without overwritting the production data. It sounds like your afraid to
use the Recovery Storage group as it was meant to be used.
I've done it many times for my customers. Make sure you read the MS doc on
We are trying to recover a single mailbox. We don't want to write over
the data store and loose current data.
We would like to use Exchange 2003 Recovery Storage Group. But we're
afraid the restore will write over current data.
Our current plan is to set up a temporary Exchange server, restore
Orin,
No need to be afraid. Follow the instructions for creating the Recover
Storage Group. When you bring up the TDP restore screen it will tell
you that a recovery group exists and that all restores are going into
that (just above the list of exchange backups to restore).
The many
Thanks!

Orin,
By default, Data Protection for Exchange will restore
data back into the live Exchange Server and into the
original storage group and database. The Microsoft
Exchange Server requires that the database be dismounted
for this operation. If that is not what you want,
it would help to
Is there a way to redirect a TSM Data Protection for Exchange restore to
an alternate location? When I try a restore TSM first asks to close the
datastore.
