What happens if the server with the exchange server dies? We have the database backed up, but how recoverable is it?

Also, can we load balance the exchange store? Do we need one shared hard drive or does it replicate the database onto the other server live?

ps. I'm using exchange 2007

It's preferable to bury it - you shouldn't keep it out for a long time - might stink.
Jk - depends on what you want to do - if you want to bring back the exchange functionality. Bring up another server with same configuration - o/s - drives - ip address - and run the command /recoverserver (similar to disaster recovery switch on legacy exchange boxes.) Ref Link

Well, if its good - we can use it to recover on some other server using either recover switch or using RSG.

Well, you can use both features
One of the cluster type (for E2k7) using shared drive (similar to what E2k-E2k3 had) its called Single Copy Cluster
The second type of cluster type (for E2k7) requires you to create cluster between two nodes (not sharing physical drive) its called Continous Cluster REplication.

Last type (though not exactly a cluster type) actually copies the database to a different server (different name - no cluster linked between both) - this type is called Stand Alone Cluster Replication.

When the server dies you restore from tape or whatever you have the backup on. You don't necessarily need to have the C drive backed up, although it's far better if you do. The recovery process involves re-installing Exchange with a special switch and then you restore the stores. All of the configuration data is in AD so it's a good plan for you to have separate boxes for AD and Exchange.

You cannot load balance the stores if you mean duplicating the information and having both running at the same time. You can certainly implement a resiliency solution such as CCR or SCR to provide an active/passive approach.

I'd do some reading up and get some book from amazon by Jim McBee as a starter.
