Ok, in order to educate them I need to understand what we can do for £x and what spending an extra £y would give us. Sticking with Exchange 2007 and using SCR would be free but having not used it I don't know how successful it would be and how long it would take to failover. Employing Exchange 2010 and DAGs would cost us somewhere in the region of £4000 once we have purchased the Exchange 2010 licences, Windows 2008 enterprise and updated our backup software. Can anybody emlighten me in what can be achieved with SCR and roughly how long it would take to failover? Thanks

You need to educate the people in charge, the business unit, and anyone else involved in the decision making process. It's your job to show them how much it will cost to meet certain SLAs. If they need e-mail up in 15 minutes after a complete site failure, you need some type of automated replication/clustering capabilities and they need to know how much that costs. They'll either re-evaluate the SLAs or pony up the cash for your proposed solution. - Sean On Wed, Aug 11, 2010 at 6:54 AM, <greg.swe...@actsconsulting.net> wrote: Without DAGS you would be looking at some form of server cloning to a backup virtual or physical box or a third party software that is keeping a synced up copy of the system. The problem you run into here is that unless the program is Exchange aware and handling logs files and DB appropriately or is shutting down the service when it does its snapshot (a uptime issue) your database would be dirty if you had to powerup that remote server and would not be guaranteed to have a good store mount.

We have about 150 mailboxes. I am looking to deploy Exchange 2007 or 2010 to host these mailboxes and to also provide DR functionality to a remote site. We have appropriate hardware. My question is what additional functionality would I gain from using Exchange 2010. Bearing in mind I have the go ahead to purchase 2 copies of Exchange 2010 but doubt I will have the budget to buy 2 copies of Windows 2008 Enterprise so that stops me using the DAG functionality? Can I still have some form of redundancy to a remote site without DAG in 2010. We can survive without email for 15 minutes so a degree of manual intervention is OK, but any longer and we start to miss SLAs etc Thanks in advance Andy This message has been scanned for viruses by BlackSpider MailControl <http://www.blackspider.com/> Click here <https://www.mailcontrol.com/sr/ulgG60l95WTTndxI!oX7Ugh17PFMs1U9Uk2aaOPfw22gAkNCtz0yQ+Bz+fmahuI51+NLDk51HxNPZmPPpGmKJg==> to report this email as spam.
