Bob Fronk bfronk@xxxxxxxxxxxxxxxx <http://www.davishelliot.com> _____ From: Lloyd Williams [mailto:Williams@xxxxxxxxxxxxxxxxxxxxxxx] Sent: Wednesday, July 20, 2005 1:06 PM To: [ExchangeList] Subject: [exchangelist] Redundant Exchange System http://www.MSExchange.org/ My management would like me to implement an Exchange system with some sort of server redundancy. The idea would be two separate mail servers, one being a backup of the other. Mail coming into server 1 would also get stored on server 2. Both machines would be online all the time and maybe a replication process would run every 15 minutes that would synchronize the two. In the event server 1 crashed, server2 would take over until server 1 could be fixed and got back on line. From what I have read I don't think this functionality is built into Exchange I think I would need a third party product. Does any one have any experience with such a set up.
