Dell NetWorker Deploy 2023 key terms

Central host that runs the NetWorker services, stores the client configuration and media database, and schedules and coordinates backups and recoveries across the data zone.

The complete set of NetWorker components managed by one NetWorker Server, including its clients, storage nodes, devices, and the server itself.

A configuration object on the NetWorker Server that identifies a machine to protect, listing its hostname, assigned schedules, save sets, and the storage node used for its backups.

A unit of backup data produced by one client backup, typically a filesystem or application dataset, tracked individually so it can be browsed and recovered on its own.

The scope of a scheduled backup such as full, incremental, or level-based, which determines whether all data or only changes since a prior backup are written.

A backup that captures only files changed since the most recent backup of any level, reducing backup time and media consumption but requiring prior backups for full recovery.

A named calendar of backup levels applied to client save sets, defining which days run full, incremental, or skip actions over a defined period.

A rule that determines how long backed-up data remains recoverable before its media can be recycled or relabeled for reuse.

The portion of a save set's retention during which its entries can be browsed in the client file index for file-level recovery; after it expires only save set recovery remains possible.

A per-client database of backed-up file and directory entries that enables browsing and selective file-level restore operations.

The server-side catalog recording every volume, its pool, save sets stored on it, and expiration status, used to locate data during recovery and control volume reuse.

A special save set containing the NetWorker Server's configuration and databases, used to rebuild a server after failure or disaster.

A host that owns backup devices and writes or reads backup data on behalf of the server, allowing backup traffic to be distributed across the network.

A configured backup target such as a tape drive, autochanger, or advanced file type device, that the storage node uses to write and read backup volumes.

Advanced File Type Device: a disk-based backup target managed as a device with configurable volume sizes, used for fast backups and clones without tape hardware.

A single unit of backup media, such as a tape or a file on disk, that is labeled, assigned to a pool, and tracked in the media database.

A logical grouping of volumes with common properties and intended use, such as a default pool or a clone pool, from which devices draw media for backups.

The process of writing an identifier and pool assignment onto a volume so NetWorker can recognize and manage it, overwriting any prior contents.

A copy of a save set written to a separate volume or pool, providing an additional protection copy independent of the original backup media.

A policy that automatically copies backup save sets from a primary device to another storage location, often disk to tape, to extend retention or free fast media.

A recovery method that restores an entire save set without browsing its contents, used when the client file index is unavailable or expired.

A restore in which data from one client is recovered to a different client or host, subject to access permissions and configured remote access.

The Java-based administrative interface used to configure clients, devices, and policies, and to monitor and report on backup activity.

A command-line utility for viewing and modifying NetWorker resource attributes, commonly used to script client and device configuration changes.

A command-line monitoring tool that displays current NetWorker server activity, including running backups, waiting sessions, and device status.

A background NetWorker process such as nsrd, nsrmmd, or nsrexecd that provides core services like scheduling, media handling, and client-side execution.

The NetWorker client daemon that runs on protected hosts, authenticates the server, and launches save and recover processes on request.

A container in the NetWorker workflow model that groups workflows, and thereby backup actions, under shared configuration for a set of clients.

A defined sequence of actions within a policy that runs backups or clones for selected clients on a schedule.

A single task inside a workflow, such as a backup or clone operation, with its own schedule, destination pool, and retention settings.

A feature allowing a client to send backup data directly to a storage node's device, bypassing the NetWorker Server for improved throughput.

The process by which NetWorker verifies the identity of servers, clients, and users, often using host certificates or external identity sources.

A defined set of NetWorker users granted specific privileges, such as monitoring, recovery, or configuration rights, through assigned roles.

The rules and role assignments that determine which users and hosts may view, change, or recover NetWorker resources and data.

The collection and presentation of backup statistics such as success rates, media usage, and failures, used to verify protection and capacity trends.

A record of NetWorker daemon and job activity, including errors and warnings, used to diagnose failed backups, devices, or recoveries.

The process of rebuilding a failed NetWorker Server from a bootstrap save set and reinstalling the server software and configuration.

A maintenance operation that merges incremental save sets into a synthetic full backup, reducing the number of save sets needed for recovery.

The act of overwriting an existing volume's label so it can be reused, permitted only when the volume is expired or explicitly forced.
