Attached is my design of current architecture we are proposing

1. This was the design for the environment, I understand VMWare level backup requires an Vcenter to communicate from Avamar
2. Understanding the architecture of VMWare backup , Proxy will be on ESXi and snap shot will get created on the data store .
3. Now Lerma ESXi is managed by Mexico Vcenter .
4. If I need to configure to VMWare level backup of Lerma which should reside on Lerma Avamar node itself  .
5. If I am not wrong and as per my understanding of VMWare level architecture , Campus Avamar will communicate to Mexico Vcenter and Vcenter will communicate to proxy which is residing on Lerma ESXi and Vcenter will create a snapshot on the data store which on Datastore which is on Campus storage, once the snapshot  is created on Campus data store again Vcenter will initate to proxy to carry that Avamar  which is on Campus itself , If I am not wrong .
6. My understanding is only the communications has to happened between Lerma Avamar & Mexico Vcenter and rest snapshot creation will happened on Lerma itself ? correct me if I am wrong

Thanks in advance
