NetWorker 8.2 SP2 is released!


It is release, Build 926.

New features and changes in NetWorker 8.2 SP2

The NetWorker 8.2 SP2 software contains the following new features and enhancements, such as:

OVA files for the NetWorker 8.2 SP2 VMware Backup Appliances

Networker 8.2 SP2 provides the following OVA files for the 0.5 TB, 4 TB, and external proxy VMware Backup Appliances, in addition to the appliance for upgrading your OVA version.
The following table provides version information for the new OVAs.

File name Description
EBR-0.5TB- NetWorker 8.2.2 OVA for the 0.5 TB VMware Backup Appliance
EBR-4.0TB- NetWorker 8.2.2 OVA for the 4 TB VMware Backup Appliance
EBR-Proxy- NetWorker 8.2.2 OVA for the External proxy that supports EXT4 backup and recovery
EbrUpgradeFrom70To-7.1.62-3.iso NetWorker 8.2.2 ISO file for upgrading the OVAs

If you previously deployed OVA versions, you must apply a patch before upgrading to OVA version When you download the OVA from a document displays which contains the patch links with instructions for installation. After applying the patches, you may then proceed to upgrade from OVA version to OVA version If you are not running OVA version, you do not need to apply the patches and can upgrade directly to OVA version
EMC strongly recommends also upgrading your NetWorker Server and Storage Nodes to Networker 8.2.2.

Removed link suspend during mount operation

NetWorker no longer suspends a consistency group’s continuous replication during snapshot import.

JRE 8 now supported

NMC for NetWorker 8.2 SP2 supports systems running Java Runtime Environment version 8.

Reduced name resolving to use only when explicitly needed

NetWorker 8.2 SP2 reduces name resolving by eliminating name resolving calls that are not directly related to client connectivity.

Notification when trying to add a NetWorker server that cannot be added

In NetWorker 8.2 SP2, a dialog box appears with an error message when you try to add a server that cannot be added for the following reasons:

  • the server is already in the server list
  • the server does not exist
  • the server is not a NetWorker server.

Flag added to nsradmin -C command for NSR storage node check

In NetWorker 8.2 SP2 you can perform a NSR storage node check using the nsradmin -C command with the -s option. NetWorker will look up and ping hostnames for each resource in DNS, and list all devices configured for the specified storage node.

For example, to check a NSR storage node named "charles," type the following:
nsradmin -C -s charles "NSR storage node"

Option added to increase the maximum device limit up to 1024

NetWorker 8.2 SP2 allows you to increase the device limit up to 1024 by setting the macro environmental variable NSR_MAX_DEVICES. In previous releases, the maximum device limit is 750.

nsradmin visual mode supported on Windows

NetWorker 8.2 SP2 adds support for running nsradmin in visual mode on a Windows system.

nsradmin -C checks for hostname mismatches

NetWorker 8.2 SP2 adds an extension to the nsradmin -C command to match the hostname attribute of a NSR peer information resource with the name attribute in a host’s NSRLA resource. This allows you to find clients with a mismatch between the NSR peer information resource and the NSRLA resource.

Flag added to nsradmin -C to correct RAP configurations

In NetWorker 8.2 SP2 you can add a flag to the nsradmin -C command to automatically correct errors in RAP configurations when possible. Use the following command:

nsradmin -s server -p nsrexec -C -y "NSR peer information"

For example, if you specify the command with these variables:

nsradmin -s -p nsrexec -C -y "NSR peer information"

Output similar to the following should appear:
Validate / autocorrect "NSR peer information" resources
Synopsis: For each NSR peer information resource in charles’s
NSRLA database, verify the ‘NW instance ID’ and ‘certificate’
attributes match those found in the peer’s NSRLA resource.
Peer 1 of 1
Instance ID: 6fc4d703-00000004-
* The "NSR peer information" resource for
in’s NSRLA database is out of date. The
"NW instance ID" attribute does not match the one in’s NSRLA resource. To correct the problem,
delete the NSR peer information resource for in’s NSRLA
Matching certificates: Corrected
NSR peer information resources checked: 1
RAP connect errors: 0
RAP query errors: 0
Resource mismatches: 1
Resources corrected: 1
Peers with mismatched certificates/instance IDs: butterball.
Corrections were made to the NSRLA databases of the following
Total errors: 1

LibDDBoost library updated to

NetWorker 8.2 SP2 uses the libDDBoost library version

NSR usergroup check added to nsradmin RAP validation

NetWorker 8.2 SP2 allows you to check for clients in a NSR usergroup configuration to identify hosts with missing or incomplete DNS entries by using the nsradmin RAP validation command:

nsradmin -s server -C "NSR usergroup"

Non-optimized backup recommended for Windows deduplication volumes

Due to recovery performance issues observed with optimized backup for Windows deduplication volumes, EMC recommends non-optimized backup.

When you set the backup to non-optimized, the deduplicated files get rehydrated in memory before they are backed up. This type of backup requires you to enable VSS. If you disabled VSS (for example, by specifying VSS:*=off in the Save Operations attribute), the backup will potentially back up the chunk stores unnecessarily.

To back up the deduplicated volume, EMC recommends using block based backup (BBB) instead. If you still require optimized backup, you can add VSS:NSR_DEDUP_NON_OPTIMIZED=no to the Save Operations attribute to restore settings to the traditional (non-BBB) optimized backup, however EMC does not recommend using this setting as the recovery performance issues may result in an unusable backup.

Added tools in NMM packaging

NetWorker 8.2 SP2 adds two tools in the NMM packaging to improve usability:

  1. A tool to find the required save sets to scan-in for expired/non-browsable save sets.
  2. A tool to recover deleted databases.

Media database snap session ID attribute query-able with mminfo

NMM backups of VSS libraries are stored in the media database with few attributes that are specific to snapshot backups. One such attribute is snap session ID. This attribute has the same value for all backups that are part of the same VSS backup set. In previous versions of NetWorker, the snap session ID attribute can only be reported on, and is not a query-able attribute.

With NetWorker 8.2 SP2, you can query the snap session ID attribute with the mminfo command. This new feature enables you to find all backups that are part of a backup set.

Once you have a snap session ID for one save set, you can find all save sets that have the same snap session ID. This information is useful for scanning in required save sets that have expired or are no longer browsable, and makes the task of finding required save sets much easier.
