Why each option
VMware vSphere Storage APIs - Data Protection (VADP) provides a method for centralized, agent-less backups of virtual machines without consuming excessive ESX host resources. This approach allows backup operations to be performed off-host and can leverage LAN-free data transfer methods.
The vSphere Storage APIs - Data Protection (VADP) enables backup applications to perform centralized, off-host backups of virtual machines by leveraging technologies like snapshots and Change Block Tracking (CBT). This design offloads the data transfer and backup processing from the ESX host to a dedicated proxy server, often allowing for data movement directly from storage to the backup target, which can be 'LAN-free' or reduce LAN impact.
VADP is designed for agent-less backups at the virtual machine level from the hypervisor, not relying on backup agents installed within the guest operating system for the primary data transfer.
A key benefit of VADP is to offload backup processing from the ESX host, thereby reducing its resource utilization during backup windows, rather than increasing it.
VADP facilitates centralized backup management and off-host processing for efficiency and scalability, making decentralized or on-host backup less relevant to its core benefits.
