"Backup" 2010 Exchange Server

Hello All,
I would like to setup a secondary exchange 2010 server for redudancy. They are shutting off the power for our corporate office (where our single install of exchange is installed) for a day and I want to be able to setup a secondary server offsite to handle delivering our mail during the outage. I would like to be able to use this server in the future as a fail safe for mail. What is the best way to go about doing this? Are there 3rd party apps or solutions for this kind of thing?

hmm .. not really good news for you , I struggle with the same issue . this is what small business usually use , standard edition does not support clustering through DAG .

Look at this thread ; has all recommendation and possible workarounds from Microsoft MVPs :
http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/5ec18988-3745-41ca-b955-35e4895af413/

so basically , you need another exchange in an isolated environment ; then you should backup and restore the data store in a regular basis.

I use Microsoft DPM to backup exchange . it's a decent tool.

another option is to migrate into a managed email system ( e.g. Google) . that's the path that small businesses are moving toward - using cloud services.

Are you looking just for backup or i guess for Redundancy .... High Availability ?

HA meaning that if email server on 1 site goes down other site or server can take over and not affect users functioning ?

Also what is the version of Windows ... if Windows 2008 R2 you can use Native Windows backup as well .... no extra cost :) $$$$

DAG is not an option with Exchange server standard , it requires enterprise edition.

So the only option is to phyically move the server to another location if I know there is going to be an power outage for an extended period of time?

akhalighi: Please read this or any article on the Internet

Yes DAG is supported in the Exchange 2010 Standard edition
http://blogs.msexchange.org/walther/2009/10/27/yes-dag-is-supported-in-the-exchange-2010-standard-edition/

For DAG you need Windows Enterprise and Not Exchange :) cause Cluster works with Ent Windows.

DAGs are available in both Exchange 2010 Standard Edition and Exchange 2010 Enterprise Edition. In addition, a DAG can contain a mix of servers running Exchange 2010 Standard Edition and Exchange 2010 Enterprise Edition.

Rancy , no problem man .. I appreciate the inputs . it's great news and here is a learning curve for everyone. I am actually glad to know standard edition supports DAG. however most of the small to medium businesses are using windows standard edition.

So .. now our friend "portillosjohn" has one server and basically needs to know what can be done for their extended power outage .

portillosjohn , do you have any other offices connected over VPN or so ?

portillosjohnAuthor Commented:
Yes we have another office that we are going to use as a secondary data center connected via vpn.

Manpreet SIngh KhatraSolutions Architect, Project LeadCommented:
So as said you can get the New server as Standalone or in DAG and then move across all information to point to the new server and then move the old server out ......

But you my buddy have to decide with what do you want to proceed.

If you can connect through VPN and you have no issues with using windows enterprise edition ( licensing) ; I vote for Rancy's suggestion to go with a DAG setup ; that's the perfect solution for exchange server redundancy .  Note that your current exchange server should also run with windows enterprise edition.

If you don't have access to those licenses ; you can consider virtualizing your exchange server and replicate that VM to your alternate site . this way you can run it in other location until main office is back up , you need to copy the VM back before using it again in your main office.

do you have a VMware environment ? any ESX servers ?
