I currently have a 2 node Exchange 2007 CCR cluster. It's been working fine for about a year now with the Information Store service on the passive node turned off and set to "Manual".
I am using an off-site backup solution (Evault) that I'm trying to configure to backup Exchange 2007 from the passive node (as recommended by Microsoft). In working with their support, they metioned that the Information Store service on the passive node should be started. This doesn't make much sense to me, and from what I remember, goes against Microsoft's recommendation that Information Store services should not be running concurrently on a cluster.
Does anybody have any info in this? Should the service be running on both nodes at the same time? Is there a Microsoft article explaining this?
