EMC NetWorker
This section includes both general and deduplication guidelines as well as other useful information
for EMC Networker.
EMC NetWorker Application Overview
EMC Networker is based on a client/server architecture and comprises several distinct components:
•
Console server: all EMC NetWorker servers and clients are managed from the NetWorker
Console server. The Console server also provides reporting and monitoring capabilities for
the servers and clients.
•
Web browser: the Console server is accessed through a graphical interface that can be run
from any computer that has a web browser. Multiple users can access the Console server
concurrently from different browser sessions. A computer that hosts the web browser can also
be a NetWorker client.
•
Datazone: a datazone is a single NetWorker server and its client computers. Datazones can
be added as backup requirements increase.
•
NetWorker server: NetWorker servers provide services to back up and recover data for the
NetWorker client computers in a datazone.
•
NetWorker storage node: a NetWorker storage node can be used to improve performance
by offloading much of the data movement from the Networker server involved in a backup or
recovery operation.
•
NetWorker client: a NetWorker client computer is any computer whose data must be backed
up. The NetWorker Console server, NetWorker servers, and NetWorker storage nodes are
also NetWorker clients.
