This record shows how EMC Avamar allows to backup an EMC or a NetApp NAS device (an EMC VNX in this case) using the NDMP protocol. During the first backup, the NAS device create a Level 0 snapshot and sends the data to the Avamar NDMP Accelerator node which chunks the data and send only unique blocks to the Avamar server. All the subsequent backups are done requesting a Level 1 snapshot on the NAS device. No other full backups have to be done after the first one.
