  • Question

  • Hi,

      I have following setup in our office environement.

      Domain controller  : Windows 2008 R2 on Dell Poweredge R710

      ADC : Windows 2008 R2 on Dell optiplex 780

      Exchange 2010 DAG 1/ CAS / Hub Transport  : Windows 2008 Enterprise R2 on Dell Poweredge R710

      Exchange 2010 DAG 2/ CAS  : Windows 2008 Enterprise R2 on Fujitsu Econel S200

     

      Currently i have only the 'Windows server backup' in place to backup all these servers.Can anyone please suggest a reliable disaster recovery setup for this environment. I want to have a parallel setup(of course with different hardware) which will be kept separate from the main network, in case of a disaster i can just plugin these parallel setup into the main network with the necessary backups restored.

      Is it possible to restore the windows server backup to a different hardware ?

    Thanks..

  • Hi Thomas, 

    Question:   Is it possible to restore the windows server backup to a different hardware? 

     

    Answer:  NO , it is not possible with Windows server backup( You can only restore to different hardware provided, they have same make, model, and configuration (identical hardware). Bottom line is they should have same HAL.  http://support.microsoft.com/kb/249694


    Scenario Supported
    System State Recovery to the same instance of Windows Server 2008 or Windows Server 2008 R2 Yes
    System State Recovery after BMR / Full Server restore to the same hardware Yes
    System State Recovery after BMR / Full Server restore to different hardware No
    System State Recovery after Full Server restore (without BMR) to the same or different hardware No
    System State Recovery after a new installation of Windows Server 2008 or Windows Server 2008 R2 on new hardware or same hardware No

    Answer: yes , if you use third party backup tools like symantec Backup Exec etc. 

    Btw, if the question is about AD disater recovery, it should be in AD forums not Exchange. thanks a lot guys

  • What do you mean by different hardware? Do you mean to say if the current hardware fails, will you be able to restore on new Hardware? 
    If thats the thing, than YES. As long as the server name is the same, you will be able to restore it.

  • Hi Gulab,

      Thanks for the reply.

      I was asking about the restoring of the domain controller also to a different server with a different hardware specification or make.

      My question is if both my DC and ADC are completely destroyed then how will i recreate the environment with a set of different servers which will of course be of a different make.

  • What I understand from you is

    1. Want disaster recovery for site and easily access the date when servers go down

    2. it should not be connected to main setup. 

    You can try Exchange site resilience. It you can one exchange server in remote site with all the roles and configure DAG to replicate the data bases. off corse, you have make sure several other things as mentioned in the article (http://technet.microsoft.com/en-us/library/dd638137.aspx)

    or if you want simple back 

    1. Configure all exchange servers as Image backup 

    2. backup Exchange Databases daily incremental and weekly full. 

    When disaster strikes, 

    you can restore image in different hardware and restore the databases from backup.

  • Thats one good suggestion from v_2udan

    My question is if both my DC and ADC are completely destroyed then how will i recreate the environment with a set of different servers which will of course be of a different make.
    Answer: If something like that happens than you will have to introduce the new DC with the same name, IP and restore the System State Backup.
