Exchange 2003 redundancy


I am looking fo a way of getting some redundancy for my Exchange 2003 system, we currently have one gateway exchange server and for Exchange server for data stores, I would idealing like to have dulpicate servers on standby which I could switch over to if on were to fail, at the moment if one was to fail I would have to rebuild and restore with my backsups which would take time.

The exchange servers are all virtual running on ESX\ESXi.

What are the best practices for Exchange 2003 as I normally work in Exchange 2007 / 2010 which is easier to build in reducdancy.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.


we typically use CA Arcserve Replica to mirror Exchange 2003 VMs to a fallback VMware Hosts with local (cheap) storage for desaster scenarios.

The Best way to implement redundancy for Exchange 2003 is build Windows cluster.

You can build an active passive cluster for your scenario. The article will be of your help

Best practice is using Exchange 2003 Clustering Feature. Guide is here

Or moving to Exchange 2010 is best solution. As next year onwards Exchange 2003 support ends from MS.

I don't think you have an option to build Exchange 2003 cluster because Exchange needs to be re-installed after configuring Windows Cluster

So your best options is in VMware itself by taking VM Snapshots.

By the way Exchange 2003 is not supported in virtual environment
