Avamar NDMP Accelerator Overview

EMC’s Avamar backup and recovery solutions provide the ability to deduplicate your data at the source before sending the data over the WAN or LAN.  This opens up all sorts of opportunities for businesses with widely distributed remote sites and greatly reduce the amount of data that is backed up.  Avamar also provides the ability to replicate itself to another offsite location which could essentially eliminate the need for tape backups.

So now, for example, you could have your primary datacenter with a SAN/NAS (EMC Celerra for this example) and several small remote offices with no local IT staff.  Using Avamar you are able to back up those remote sites to an Avamar node(s) at the datacenter with no local intervention at the remote sites.  All of your remote sites are now backed up over the WAN, deduped and consolidated at your datacenter.  But what about backing up your NAS at the datacenter?  It would make sense to dedupe and back this data up to the Avamar as well and eliminate multiple backup systems.  How is this done?  Enter the Avamar NDMP Accelerator.

The Avamar NDMP Accelerator uses the standard NDMP Protocol to backup your NAS datastores (Celerra and NetApp) just like you would use NDMP to tape.  The appliance must be located on the same LAN as the storage device being protected.
