  • Defrag and move Exchange database

    Hi,

    I am looking at the guide made for Move and Defrag Exchange database.

    http://www.techemperor.com/2008/02/16/h ... harddrive/

    I understand all the steps except the last bit regarding pointing Exchange to the new defraged database location....do I follow the steps:

    1. Open your Exchange System Manager Console
    2. Expand the tree until you see the First Storage Group
    3. Right Click on the Mailbox store whose Database you wish to move and click Properties
    4. Click on the Database tab
    5. Click Browse
    6. Select the new location for the Database
    7. WAIT FOR HALF AN ETERNITY FOR THE GIANT DATABASE TO BE MOVED.

    I am concerned will this OVERWRITE my new defrag database by moving the original again or is Exchange smart enough to see it existing already and simply "point" to the new DB? The original DB can then be deleted? Thanks

    Re: Defrag and move Exchange database

    Why do you want to defrag your database?
    It is not something that must be done, or is recommended. It is not risk free and is slow. You are looking at downtime (that is complete downtime). The process goes through at between 1 and 4gb per hour, so if your database is 50gb in size you could be looking at 48 hours downtime.

    The article you have pointed to is a rather poor article. It doesn't explain things in any great detail. You normally do not move the database files manually. You allow Exchange to do so. If you are moving the file and wish Exchange to just update the location then there is a different procedure for doing that. It is not something I have done before - but then I don't do offline defrags of Exchange 2003 databases for any reason whatsoever.

    Simon.

      I've never done the defrag before, since like Sembee said, it's not something that must be done and takes forever and a day to complete.

      I have, however, successfully moved the stores to a new drive on the same server. That was a piece of cake and didn't take long to finish.
