Hello to all, I recently implemented Exchange 2003 in my org. Just about done moving all the mailboxes from the 5.5 server. I was surprised to see my backup time dramatically increase on the new server and the amount of data being backed up as well. BTW I am running a windows 2003 cluster. I just realized that the ShadowCopyComponetns (system state) on the active node is almost 54G compared to about 250MB on the passive node. It looks to me like some how the IS is being backed up by itself and again in VSS on the windows side. Any thoughts as to how can I prevent this from happening. Thanks, Juan
