In VMware, DP supports to integrate with VMware vStorage Image to protect VMs, it supports VMware LAN-Free backup in SAN environment. It use one physical server as the backup host, this backup host could access the vdisks though SAN and has the SAN attached backup devices, hence it could do the LAN-free backup. DP will install the Virtual Environment Integration component (VEAgent) on the backup host, the VEAgent will communicate with ESX host to trigger the ESX to make the snapshot of the VMs and mount relevant vdisks to the backup host, then the backup host could access the vdisksd over SAN directly and copy the vdisks to SAN attached backup devices.
