MMMUG August Event – Exchange Backup and SCDPM 2010

We’re on a roll! The August MMMUG event is being hosted by Tony Brown. and is being held in London on the 18th August 2010.

The subject of the meeting is Exchange backup and recovery and we have Microsoft’s Anthony Tyler talking about System Centre Data Protection Manager’s take on backing up exchange and Kroll Ontrack’s offering for recovery.

Kroll Ontrack is now celebrating its 25th Anniversary as a global leader in the provision of data management solutions, specialising in data recovery, restoration, erasure and investigative products and services (

Ontrack PowerControls software for Microsoft Exchange empowers users to search, recover, extract, restore and migrate Microsoft Exchange data (

Faced with increasing hardware and administration costs together with tighter budgets, organisations are seeking more cost-effective and efficient solutions to manage ad-hoc and routine Microsoft Exchange data requests. The core functionality of Ontrack PowerControls enables System Administrators to search, recover and restore entire .edb, .pst files and granular level items, whilst retaining data integrity.

Kroll Ontrack is pleased to be demonstrating the core functionality, features and application of this invaluable Microsoft Exchange administration tool.

Recovery of data from Exchange 5.5

I had a question recently from a friend at Microsoft about a client who had got into a bit of a pickle!

They needed to restore and email from a mailbox which was 5 years old, long since deleted and on Exchange 5.5.

They did have a backup from the month end, but no idea whether the mail actually was still available or whether it was deleted before month end.

I did a little research and with the help of a couple of other Exchange MVPs Paul Robichaux and Kevin Ball I think I have a solution! We will of course not find out until I get some feedback from my friend.


So my thoughts were as follows:

One option to get this back (if it exists) would be to use Ontrack PowerControls. I’ve not done it for a while, but essentially, the idea is you recover the full database from tape and then Ontrack can open it and extract the relevant email. Of course the full tool is not free although there is a free version which might just have enough to do what is needed or at least to help you understand if the email is actually available!


The other option could be interesting! I’m not 100% sure but I believe that if you have Exchange 2003 (possibly later but not sure) you could create a database and then dismount and delete the files. Then put the recovered database (.edb file) in the same location and name it the same as the dummy database file you just deleted. At this point mounting the database should prompt Exchange to upgrade the structure of the DB to Exchange 2003 and allow you to see the mailboxes within. You would then need to create a user account and link the relevant mailbox to that account. (Thanks to Paul for the tip here)


So with a bit of luck and possibly some purchasing of tools, assuming the mail wasn’t deleted before the month end back, it should be possible to get it back!


Having posted something similar on Twitter I received feedback saying the recovery via Exchange 2003 won’t work! So I tested it!! – Yup I actually installed NTT4 and Exchange 5.5.

What I have found so far is that Exchange 2003, will create an STM file but then won’t mount the database. I believe that this is probably due to the fact that they are different organisations as I didn’t carry out a migration to Exchange 2003 instead just installing separate Orgs. I will update later with more progress!



Virtualizing Exchange


Not much insight here I know, but I was researching this topic for a friend today and thought the collection of links might at least be useful!

Microsoft Virtualization: Best Choice for Exchange Server

Should You Virtualize Exchange 2007 SP1?

Exchange 2010 System Requirements

Microsoft Support Policies and Recommendations for Exchange Servers in Hardware Virtualization Environments

Running Exchange 2003 with more than 4GB of RAM

I discovered this issue the other day whilst reviewing a design for a client.

The client planned to deploy Exchange 2003 as part of a migration from Novell GroupWise which needed to occur rapidly. There was no time to wait for and test Exchange 2007 in this case. However, it was thought that as Exchange 2007 was imminent, the hardware should be specced accordingly. Therefore, servers were purchased that were 64bit and which had 8GB of RAM.

On reading the design for 8GB of RAM I wondered whether this was a sensible configuration given that Exchange (with the /3GB switch) can only access 3GB of RAM anyway and the box was only going to be running Exchange.

After a little investigation I discovered this article:

Basically, it outlines that having over 4GB of RAM in a box is potentially detrimental to performance as it takes up part of the paged pool just to address the extra RAM which you won’t be using.

So unless you are running multiple roles on one server (not recommended) then you should either remove the RAM phsyically, or use the following switch in boot.ini

/BURNMEMORY=ammount of RAM

So for a server with 8GB


This will mean the OS will not address the extra 4GB in the server.




Calculating storage requirement for Exchange 2003

Some of you will remember we had a session on this a while back at one of the meetings.

Wel in case anyone needs it, here is a link to a great resource on how to calculate storage requirement (IOPS etc) for Exchange 2003.



Just thought I would add a few more links:

Hope it helps



Multiple Forests running Exchange

I recently answered a questions about running two Exchange Orgs after a merger.

The company required GAL sync, Public Folder replication and Free/Busy sync.

Here are a couple of useful links on the same topic



The first link details the features available and what is required to implement them and the second is about the InterOrg Replication tool.



An overview of Exchange Database utilities

Take a look at the link below for a great overview of the eseutil Exchange DB tool:



Another useful troubleshooting tool for Exchange is ISINTEG. The link below is a good reference of the usage of the tool:



The basics of ISINTEG are:


Before running ISINTEG ensure that your information store is running and any databases to be checked are dismounted.

Then run:

c:\program files\exchsrvr\bin\isinteg -s servername -test alltests
