Master the full Dell NetWorker deployment lifecycle — from solution overview and daemons through installation, administration, cloud enablement, and VMware integration.
Module 01
Dell NetWorker Overview
›NetWorker solution overview — purpose, advantages over traditional backup tools, and key use cases (file, database, VM, cloud)
›Administrative interfaces — NMC Java console vs NWUI browser interface, CLI (nsrinfo, mminfo, nsradmin), and REST API
Module 02
Dell NetWorker Daemons
›nsrd — NetWorker master daemon responsible for policy scheduling, device management, and client communication coordination
›nsrexecd — remote execution daemon running on all NetWorker hosts (server, storage node, client) for remote command execution
›nsrindexd — client file index daemon managing the browsable file backup catalog stored on the NetWorker server
›nsrmmdbd — media/resource database daemon managing device registration, volume labels, and save set metadata
›nsrlogd — logging daemon collecting NetWorker system log entries; nsrsnmd — SNMP trap daemon for monitoring integration
Module 03
Dell NetWorker Installation and Configuration
›NetWorker architecture — server + storage node + client data flow, backup streams, parallelism (target sessions), and buffer size tuning
›Installation procedure — OS prerequisites (RHEL/Windows), NetWorker package install (rpm/msi), license registration via NMC, and NWUI initial setup
›Client configuration — client resource creation, save set definition, backup command attributes, group assignment, and client parallelism
›Protection Group and Policy — creating policies, workflows, actions (backup/clone/snapshot), and scheduling (daily/weekly chains)
›Backup options — synthetic full backup (less data movement), block-based backup (BBB for databases), and snapshot management with PowerSnap
›Backup device types — AFTD (Advanced File Type Device), VTL (Virtual Tape Library), physical tape, DD Boost target — media pools and auto-cloning setup
Module 04
Dell NetWorker Administration and Management
›NetWorker security — AuthC (authentication service) replacing legacy NW server authentication, user groups (Administrator, Operator, Monitor), and LDAP integration
›NMC server management — notification configuration (email alerts on backup failure), parallelism settings, report scheduling, and multi-tenancy (datazone)
›NetWorker recoveries — directed recovery (recover to different host), browsable recovery (from client file index), save set recovery (from mminfo metadata)
›Database management — media database (mmdb) backup using nsrdr, resource database (res) backup, and client file index (CFI) rebuild procedures
›Capacity management — monitoring device utilisation, volume recycling, save set expiry, and browsing retention policy impact on storage consumption
›CloudBoost configuration — deploying CloudBoost appliance (virtual), connecting to NetWorker as an AFTD device, and directing backup streams to cloud object storage (S3/Azure/GCP)
›Cloud Tier setup — configuring DD Cloud Tier on PowerProtect DD, creating cloud units, and setting up automated tiering policies for aged backup data
›NetWorker Virtual Edition — deploying NVE OVA in vSphere, initial configuration, licensing, and use cases (cloud-native backup for AWS/Azure workloads)
›Manage and monitor — tracking CloudBoost job throughput, verifying cloud tier data recall, and monitoring cloud capacity consumption from NMC
Module 07
Dell NetWorker and VMware Integration
›NetWorker vProxy architecture — vProxy appliance role as VMware backup proxy, communication with vCenter, vSphere API for Data Protection (VADP)
›Deploying vProxy — deploying vProxy OVF in vCenter, registering with NetWorker server, configuring proxy resource settings, and verifying proxy connectivity
›VMware backup configuration — creating VMware client resource in NetWorker, selecting VM containers (datacenter/cluster/host/pool), and VADP transport modes (SAN/HotAdd/NBD)
›Backup types — full VM backup (image-level), incremental (CBT-based changed block tracking), and application-consistent snapshot with VMware Tools quiescing
›VMware recovery — instant access (mount backup as datastore), full VM restore to original/alternate location, and individual VMDK recovery from NMC

Full Curriculum
7-Module D-NWR-DY-23 Programme
Complete NetWorker deployment curriculum — from architecture overview and daemons through installation, administration, monitoring, cloud enablement, and VMware integration.
›NetWorker solution — enterprise backup/recovery platform supporting physical, virtual, and cloud workloads with centralised policy management
›Prerequisites — supported OS matrix (RHEL 7/8, Windows Server 2019), RAM/CPU minimums, Java version for NMC client, and port requirements (7937-7939, 9000-9001)
›Installation steps — install NetWorker Server package, start services, register license in NMC License Manager, and complete NWUI initial setup wizard
›Client resource creation — hostname/IP, OS type, backup command (save), save set (all or specific paths), and parallelism settings
›Backup device configuration — creating AFTD directory device, formatting, labelling a volume, and setting target sessions for parallelism
›Backup options — synthetic full (merges incrementals without reading client), BBB (block-based for databases), and PowerSnap snapshot integration
›AuthC service — replacing legacy NW Authentication, LDAP/AD user group mapping, creating NetWorker user groups with role-based access (Administrator/Operator/Monitor)
›NMC server management — email notifications for backup failure/success, parallelism tuning (max sessions per server), multi-tenancy datazone configuration
›Directed recovery — recovering data to a different host than the original client, specifying relocation path, and verifying recovery success
›Browsable recovery — using NMC/NWUI file browser (requires active CFI), selecting files/directories, and initiating recovery
›Save set recovery — recovering using mminfo to identify save set ID, nsrrecover with -S saveset_id flag, bypassing the CFI
›NetWorker database management — nsrdr utility for media database bootstrap backup, resdb resource database backup, and CFI manual rebuild (nsrck)
›NMC Monitoring workspace — active backup sessions panel, device utilisation gauges, policy workflow completion status, and alert notification inbox
›Log analysis — /nsr/logs/daemon.raw on Linux or C:\Program Files\EMC NetWorker\nsr\logs on Windows; common error code reference
›mminfo command — mminfo -avot (all save sets), filtering by -c (client), -t (time), -v (volume), -S (save set ID) for recovery planning
›nsrwatch — terminal-based real-time monitor showing active sessions, device I/O, and parallelism consumption
›Scheduled reports in NMC — Backup Statistics (size/duration trend), Client Coverage (which clients have recent backups), and Data Domain capacity reports
›CloudBoost deployment — deploying virtual CloudBoost appliance, connecting as DD Boost device to NetWorker, and configuring object storage credentials (S3/Azure Blob/GCS)
›Cloud Tier on PowerProtect DD — enabling Cloud Tier license, creating cloud unit (S3/Azure), and setting file system age-out policies for automatic tiering
›NetWorker Virtual Edition (NVE) — deploying NVE OVA in vSphere or cloud marketplace, initial configuration wizard, and directing cloud-native client backups
›vProxy architecture — vProxy virtual appliance deployed in vCenter, registered as NetWorker client with VADP backup role, communicating via VMware vSphere APIs

›Transport modes — SAN transport (FC/iSCSI LUN direct read), HotAdd (vSCSI attach to vProxy in same datastore), NBD (network-based fallback mode)
›CBT-based incremental — enabling Change Block Tracking on VMs, verifying CBT reset trigger events, and monitoring incremental backup size vs full
