vStorage APIs for Data Protection (VADP) FAQ (1021175)

Purpose

This article provides answers to frequently asked questions about vStorage APIs for Data Protection (VADP).

Resolution

What is VADP?

VADP is the next generation of VMware’s data protection framework introduced in vSphere 4.0 that enables backup products to do centralized, efficient, off-host LAN free backup of vSphere virtual machines.

A backup product using VADP can backup vSphere virtual machines from a central backup server or virtual machine without requiring backup agents or requiring backup processing to be done inside each guest virtual machine on the ESX host. This offloads backup processing from ESX hosts and reduces costs by allowing each ESX host to run more virtual machines.

VADP leverages the snapshot capabilities of VMware vStorage VMFS to enable backup across SAN without requiring downtime for virtual machines. As a result, backups can be performed non-disruptively at any time of the day without requiring extended backup windows and the downtime to applications and users associated with backup windows.

What are the benefits of VADP?
 
VADP enables centralized, off-host LAN free backup of vSphere virtual machines, reduces ESX host resources to do backup processing, and enables flexible backup windows.
 
Does VADP replace the VMware Consolidated Backup (VCB)  framework?
 
Yes.
 
How does VADP compare with VCB?
 
Unlike VCB, which requires customers to download and install a separate component on VCB proxy server, VADP is built-in as a part of the backup product. The following table summarizes the key differences between VADP and VCB.
