I wonder if someone with some more experience than me can cast thier knowledgeable eyes over this and let me know if it is correct (or not):
(ESX4 all the way though)
We are backing up misc servers (server1) to Veeam1 using virtual app. mode
We are using Veeam2 to do replications of other large servers (server2) as a pull using Veeam2 using virtual app. mode
We are using Veeam2 to replicate Veeam1 to DR storage (which will go off site after pre-population) virtual applicance mode
We are moving Veeam2 and Server2/replicated Veeam1 to our DR site (the storage is going with it) - using virtual appliance mode
Veeam1 will continue to be replicated across a 37mbit link to DR site using Veeam2 - using virtual app. mode
Large servers (6TB) will continue to be replicated accross the WAN using a pull from Veeam2 - using virtual app. mode
The question is about network replication mode; even though all servers local and remote are part of the Virtual Centre site; should I be using network replication mode and the ESX agent for some form of compression; or should I use virtual appliance mode? I want to be able to harness CBT during replication (as that's the point). Thanks for reading.

Provided that you're using full blown ESX hosts, I would recommend to specify service console credentials in any way, so Veeam backup server could install small agents to handle compression/dedupe without stressing your network connection. As a result, you should see better processing rates for your replication jobs.
As far as job mode is concerned, I would definitely stick to using Virtual Appliance mode with 4 vCPU granted to backup server located on the source site. However as soon as you move your backup server to DR site, I would switch to vStorage API - network mode, in this case you will continue replicating changed blocks only.
Hope this helps!
