NetWorker datazone
A NetWorker datazone is a single NetWorker server and its client and storage node hosts.
NetWorker client
The NetWorker client software communicates with the NetWorker server and provides
client initiated backup and recover functionality. Install the NetWorker client software on
each host that you will back up on the NetWorker server.
Before you install the NetWorker client software, ensure that NetWorker supports the
specific client operating system and hardware configuration.

EMC NetWorker Software Compatibility Guide
provides the most up-to-date
information about compatibility.
NetWorker storage node
NetWorker can back up data to devices that are local to a NetWorker server or remotely to
devices on a storage node. A storage node controls storage devices such as tape drives,
disk devices, autochangers, and silos. The NetWorker server is a local storage node. You
can use a remote storage node to offload most of the data movement involved in a backup
or a recovery operation from the NetWorker server. A remote storage node improves
performance but requires high I/O bandwidth to manage the transfer of data from local
clients, or network clients to target devices. The operating system of a remote storage
node can differ from the NetWorker server.
