Distaster Recovery for Exchange Scenario
Posted on 2010-01-01
I really have a hypothetical question. Here is my scenario at our office:
SBS 2008 Premium
I had to reboot the server due to updates that rolled out last night, so I logged on early this am and restarted it. Turns out, one of the security updates blocked OWA to all my blackberry users. I started getting bombarded with text messages that we were down...etc. After 20 minutes trying to figure out the issue, I rolled back the updates and everything was fixed. I will figure out what the security issue was on monday.....but, my question for you all is this:
How can I set up my infrastrucure so that if Exchange EVER goes down...a second server kicks in?? I don't have any large corp experience in this field..and I am new to exchange. What do huge corporations do when they have to reboot their exchange servers? Does the entire company go down?? What kicks in at that point? Is it a clone server, always running? Does this make sense? I am looking for a good solution for a medium sized business which is 100% up on exchange all the time.....they NEVER EVER want to be down.
How can I accomplish this? thanks everyone!
