A data zone is a collection of clients, storage nodes, and data sources to be protected by a single backup server. NetWorker Storage Nodes. Client Much of the responsibility of backup and recovery processing belongs to the client, which takes advantage of network and backup server bandwidth to process multiple client data streams in parallel. This data stream parallelism is discussed in more detail later in this document. NetWorker includes support for client-side data compression, encryption, and password protection.
Administrative mode provides the interface for monitoring and control.
Any machine within a NetWorker data zone can be designated a Storage Node, and any supported storage device can be attached directly to it. Backups can be done locally by sending data to an attached library instead of over the network to the central server. Only the metadata about the backup is sent to the central server. The advantage is that the data movement is decentralized, which is good for performance, while the control is centralized, which is good for management. Performance Product performance has been improved in NetWorker 6 using techniques like data stream parallelism alongside simultaneous storage device operation, improved file indexing, and intelligent sharing between client and server functions.
