I have a client whose app vendor is claiming that an offline defrag needs to
be done once per quarter. This app is a document management system that uses
the Public Store (this is an Exchange 2003 Enterprise installation) for the
posting of document pointers.

My experience with Exchange (back to 4.0) has told me that you tread
carefully using eseutil, and, frankly, only when you want to compact and
recover disk space.

Has this changed? Is there a recommended frequency, and what does it buy
you other than disk space and a mild gain in performance?

Thx...

Hi Doug.
I don't believe in a standar frequency, because the database activity is
bussines dependent.
We have to see client activity, mailbox size and quantity, client activity -
mail reception, deletion and so on.
The defrag tool can be used to recover disk space, but can be used to check
database consistent and healty. It can be a preventive tool. I has some
incidents with the edb database without alerts in event viewer or logs, and a
periodic defrag raised the error.
In my experience the defrag can be done once or twice times in a year.
One more time, it depend on the organization type, downtime expected and
client and server activity.
I hope this can be helpfull.

Guy offline defragmentation should not be done if it is not needed
if there is not a lot of deletion user accounts, and so forth there will not
be much
white space and I am not seeing a reason to do offlien defragmentation.


I have seen people claiming if should be done two times a year, my experince
is telling me if you do not need it leave it alone,

if you need it why not it is not a big deal anyway

I aggree business load how they operate daily task makes a different

Cheers

I wouldn't be investing today in anything that uses public folders.
Look to software that uses Sharepoint, instead.

The usual answer to that is either "never", "hardly ever", or "as

The database itself is purged of any "views", indexes are regenerated,
free space is removed, the file size might shrink.

Nothing you do with a disk is a zero-risk operation. All the caveats
about backups apply to that defrag operaton.

Yes, well, unfortunately we weren't consulted when the app was chosen. They
became enamored of it because its a verticle-market law firm document
management system.

I'd ask the vendor what his plans are for this software in three
year's time. By then you'll be in so deep you won't be able to
extricate yourself and you may find you don't like the position you
find yourself. Being "over a barrel" ain't comfortable.

Well, at least with Exchange 2003, they should be able to get into 2013
before it hits it's extended end of life, 30 September 2008 if they don't
opt to pay for the extended support.

In all my years with Exchange, so called preventative maintenance has always
been a two sided sword and you will get advice from both sides. The third
party Exchange tool, GoExchange does offline defrags and is the companies
major selling point (personally, I would never opt for such a product).
Anyway, with all the advice, I believe the major consensus is "if it ain't
broke, don't fix it". A lot of this thought, I believe, was/is based around
the old 4.x/5.x versions, which would corrupt at the drop of a hat; 2003 is
certainly more friendly. The only reasons to do an offline defrag is if you
have moved many mailboxes off to another database or there are issues in
logs or user experiences, otherwise a defrag is best left to the online
maintenance window. However, if you choose to do a defrag, always make sure
you run an "isinteg -fix test alltests" on repeatedly on the database until
you get all zeros or two results that are the same; as an offline defrag
actually builds a brand new database which results in a "defraged"
appearance though it doesn't actually defrag the original database.

It is SQL-based, but uses Public Folders as pointers to the database entries
for Matter Information.

2008 is just three years away.

The problem is going to present itself not in whether or not something
works, but whether they'll be able to make use of features in newer
releases.

The point is, I guess, that buying into something now, knowing it has
a very short window of usefulness, is not very good business planning.
