I have a question regarding data flow in the following environment:
3 sites, each a seperate NBU domain with a 5230 appliance and multiple windows servers (2K8R2 & 2K12R2)
I use AIR to replicate backups between the sites
1 scenario is as follows:
Step 1 Exchange DAG backed up to 5230 in site A
Step 2 Backup replicated to 5230 in site B
Step 3 Replicated copy imported into 5230 in site B
Each of the above steps runs successfully and the backup is available for restore in site A and site B as expected.
Here is the question:
Whilst step 3 (Import) is taking place on the 5230 in site B I am seeing a lot of network traffic between the 5230 in site B and the exchange server (where the backup originated) in site A !! Surely there should be NO communication between the appliance in site B and 'anything' in order to perform an import of a replicated backup image ? If anything traffic between the appliances, but not back to the originating client ?
What am I missing here ?
