I would like to back up some on-prem system (SRV1) using Microsoft Azure Backup Server (MABS1), but I would like to host the MABS1 server itself on Azure as a VM and use an on-premises storage for cache/scratch (NAS1). I want to backup for Bare Metal Recovery (BMR) and that requires a MABS.
Will the traffic flow like this:
(A) SRV1->NAS1->MABS1->Site recovery Vault? Or (B) SRV1->MABS1->NAS1->MABS1->Site Recovery Vault?
