NetWorker Data Management Protocol (NDMP) save set of PowerScale NAS, with NDMP Multistreaming enabled, that has completed as "recoverable," displays 0-Bytes size in the NMC user interface.

This describes the procedure to enable Java UI debugging within the NMC user interface.

NMC initiated SQL backups fail with "Cannot run savefs: no error"

This process is intended for NetWorker backup administrators to enable Java Virtual Machine (JVM) monitoring when Java thread and heap dumps are requested by NetWorker support. This may be useful when doing advanced diagnosis of authentication-related issues.

The File Level Recovery (FLR) for Windows Virtual Machine is consistently failing. The FLR mount is successful, but the browse fails for 3-4 folders with the message "Could not get the directory content unable to retrieve file list from VM (path) Access denied."

NetWorker server deployed on Linux fails to start server services (nsrd) after upgrading to 19.7.0.x or later from an earlier release. The RabbitMQ process crashes during service startup due to a bad argument error.

Use mminfo to extract deduplication statistics for a NetWorker save set on a Data Domain; the output follows version:cloneid:backup:pre‑compression:post‑compression and shows deduplicate compression process.

You have created or updated an external authority in the NetWorker Management Console (NMC) for Active Directory (AD) using the "LDAP over SSL" option. The configuration succeeded, but AD logins fail with HTTP 404 or HTTP 500. This issue occurs because the LDAP over SSL option sets an internal authc flag "Is active directory" to "false." This option must be set to "true" when the authentication method is active directory.

NetWorker VMware Protection (NVP) vProxy Virtual Machine (VM) backups sit in "waiting to run" state for a prolonged period of time. There are no vProxy availability issues, communication between the NetWorker server and vProxies is successful. There are no alerts regarding vProxies being unavailable in the NetWorker Management Console (NMC),

How to backup Virtual (Clustered) SQL Server instance with NetWorker Module for Microsoft (NMM) using VDI command-line syntax or 'nsrsqlsv'

NetWorker server and client can backup save sets that are Common Internet File System (CIFS) shares on a Windows server or any other NAS Filer. This requires certain permissions.

After the NetWorker Runtime Environments (NRE) upgrade on a Linux NetWorker server, NetWorker Management Console (NMC) authentication fails. The system reports errors indicating that user credentials cannot be validated.

These are the general steps to replace the default NetWorker self-signed certificate with a Certificate Authority (CA)-signed certificate for the "AUTHC" and NetWorker Web UI (NWUI) services.

Tape to tape clone fails when there are multiple source tape volumes and one available read side tape device. Intermittently, load operation goes in to an indefinite loop and clone operation is eventually timing out.

This article describes how to manually use the legacy 'jbconfig' command to configure a tape library in NetWorker.

The purpose of this HOW To is to provide a main landing page for quick access to NetWorker License Triage Guide information and guidelines.

After the upgrade to v19.11.0.0, nsrdr is failing occasionally.

This KB provides an overview of the different vProxy builds and their embedded ddboost, VMware Disk Development Kit (VDDK), VMware Tools versions, and OS details. This KB requires a Dell support site user-account to access.

This article describes how to configure tape devices for PowerScale cluster nodes to avoid slow NetWorker Data Management Protocol (NDMP) backups. Add specific tape devices to each node by limiting the devices used in a NetWorker 'Media Pool'.

This article provides details of how to set the number of parallel save streams to be used for an Isilon NetWorker Data Management Protocol (NDMP) multistream backup.

The NetWorker vProxy solution is used to protect the vSphere environment. The file-level restore (FLR) fails for all Virtual Machines (VM) with the signature length error. Data Domain self-signed CA certificate has expired. Renew Data Domain certificate as shown in Dell KB 198864.

NetWorker Module for Microsoft (NMM) 19.8 through 19.10.0.4 SQL Server Management Studio (SSMS) plugin issue for databases with diff backups

A Zimbra server on a Red Hat Hyper‑V Virtual Machine (VM) shows processor and memory exhaustion during backup. The VM becomes unresponsive and must be rebooted.

NetWorker VMware Protection (NVP) Virtual Machine (VM) backups intermittently fail with the following error observed in the backup session log "Warning occurred while releasing writer resources: Error closing temp data file: Error closing file 'SAVESET_PATH' on Data Domain 'DD_HOSTNAME': [5029] RPC operation/function failure "

The NetWorker Server software cannot be uninstalled following a failed installation of the NetWorker Server and NMC components, during which a rollback was triggered. As a result of the incomplete installation state, all subsequent attempts to uninstall the NetWorker software are also failing.
