We currently have a VM ware setup that houses an exchange 2007 server VM. We have a third party that provides back up services for us through an onsite, disk to disk server. I brought disaster recovery testing and he said that the server could be brought online via a backup, but for obvious reasons couldn't be brough up in our current network (which makes sense, since the introduction of the duplicate machine would obviously break something). What then is the best way to go about testing? What would we have to accomplish or do in a test environment to bring the VM machine online safely to make sure backups are working as they should be? Thank you.
