NetWorker 8 Client Access Feature

November 5, 2012

EMC NetWorker version 8 includes many features that make the solid backup solution even better. One of those is the Client Direct feature, also known as direct file access. This technology allows NetWorker client agents to backup directly to an advanced file type device (AFTD), or a Data Domain appliance using the DD Boost protocol.

Previously, no client backups could be written directly to AFTD devices and only the NetWorker Backup Server, Storage Nodes and specific database backup Modules could write directly to AFTD & DD Boost devices. The ability for client backup data to bypass the Storage Node and write directly over the IP network to Data Domain eliminates the Storage Node as a bottleneck during backups.

With DD Boost, in addition to client direct backup, Distributed Segment Processing (DSP) allows parts of the de-duplication process to be offloaded to the NetWorker Clients resulting in only new unique data segments being sent from clients to the Data Domain, dramatically reducing IP network traffic during backup. This will usually result in decreased I/O load on those clients during backup due to the lower processing requirements of data segmentation and fingerprinting versus having to read and transfer large volumes of data. This process would normally take place on the Storage Node, but with Client Direct enabled, the Storage Node simply manages the client without handling the backup workflow.  Unless of course Client Direct is not available, in which case the data is sent through the storage node to be deduplicated and then transferred to the Data Domain.
