What are the vStorage APIs and how have they impacted virtual server backup?
VMware’s vStorage APIs, which were first introduced in version 4.0 of VMware’s vSphere, are application programming interfaces which allow third-party storage and backup vendors to integrate their products with VMware’s vSphere.
The vStorage API for Data Protection (VADP) specifically has had an impact on virtual server backup. It enables backup applications to perform file- or VM-level backup of running virtual machines by allowing for direct integration into the vSphere hypervisor. VADP increases backup efficiency and is a considerable improvement over VMware Consolidated Backup (VCB).
