Exchange 2003: New Server for Disaster Recovery RRS feed

  • Question


  • Is there any downside to installing Exchange 2003 on it using the disaster recovery switch, as described in "Recovering a Failed Exchange 2003 Server Using the Disaster Recovery Switch"?
    :\Setup\I386\Setup.exe /DisasterRecovery
    I actually used this method to restore our production server a few weeks ago. It worked so well, I'm very tempted to use it to use it for our new D.R. server.

    But I'm concerned about any unforeseen and unintended behavior if I use this to add a new D.R. server to our environment.

    I guess I'm either over-cautious or over-paranoid, I can imagine all sorts of horrible things happening (e.g., mail starts being routed to the new disaster recovery Exchange server).

    The D.R. Exchange server is part of our production Windows domain, but on a separate sub-net connected via VPN to the disaster recovery site across town.

    SAN (fiber) +--+ EX2K3 (routable class C I.P.) --------{ VPN }-------- EX2K3DR (private I.P.) +--+ D.R.-SAN (iSCSI)
    We do not have a separate Active Directory for the disaster recovery site, nor any domain controllers installed there yet.

    We are running Exchange 2003 Enterprise on Windows 2003 Standard.

  • Hi Bob,

    I wouldn't do this in production environment. It definitely breaks your existing environment and makes this DR server as a production after recovery procedure.

    If you want to simulate the situation then make an identical lab environment which is isolated from production and perform a test there.

  • If what you want to accomplish is site resilience, failover the exchange from the primary site to DR site when the exchange services fail on the primary site, geographically dispersed clusters or standby cluster would be the features for that
