well, a restore onto a new server does work. I've been in a situation where I had to do it, albeit, it does take a moment or two. You have to reassociate the mailboxes once you are done. That said, here is some more info...

never used this one but what the heck

There are a couple of products out there that can synch 2 servers over a WAN to ensure that the passive is an exact duplicate of the active. Can't remember their names at this time but I'm sure several on this list could help out.

Seem to get much better response on Exchange matters here than on the official Exchange list J

|’m in the process of planning a fallover site for our TS Farm. Farm Is based in London, failover in Northampton, far enough away from any foreseeable disaster up to a nuclear one.

Using GPs and scripting, plus replication software for document files, am reasonably confident about everything other than Exchange.

I’ve now spent a **lot** of time looking for any articles that deal with restarting Exchange on a different server. This must be something that big boys do all the time, but I can’t seem to find much reference to how Exchange actually deals with data-stores in multi-site environments, let alone in DR situations.

What I **think** I want to do is have a good on-line backup of the information stores overnighted to Northampton, and restore this into the server there. However, I have no idea if this will work. Particularly, AD knows which server each mailbox is on. While I can probably run a script to change this manually, it seems logical to me that it should be possible to move between different sites (In a non-DR scenario), and log onto different Exchange Servers, but still be able to access one’s mailbox. In fact, it would seem insane not to be able to do so.

Can anyone point me in the direction of articles about how Exchange actually works in multi-site scenarios, or, even better, how DR can be made to work (Fro preference, without £000s of software).

Many thanks,

Nick
