It is release 8.2.1.0, Build 681.

New features and changes in NetWorker 8.2 SP1

The NetWorker 8.2 SP1 software contains the following new features and enhancements, such as:

Recovery from a secondary site to a different vCenter when primary site is unavailable

Starting in NetWorker 8.2 SP1, when you clone a VM or VMDK backup to a secondary site with its own vCenter and VMware Backup appliance, and the secondary site shares the same NetWorker server as the primary site, you can recover data from the secondary site to a different vCenter when the primary site becomes unavailable.

You can select this option in the Restore tab of the EMC Backup and Recovery user interface in the vSphere Web Client.

Dual network support for proxy backup with NetWorker VMware Protection

The NetWorker VMware Protection solution for NetWorker 8.2 SP1 supports dual network configuration so that you can use separate networks for VM backups (for example, proxies deployed to backup VMware environments) and traditional backup data traffic.

You can configure dual NIC when you deploy the VMware Backup appliance and the proxy appliance.

NetApp SnapVault and NetApp SnapMirror replication to remote NetApp devices

The following support for NetApp SnapVault and NetApp SnapMirror operations to replicate data snapshots in 7-mode or cluster-mode to remote NetApp devices is available in NetWorker 8.2 SP1:

– Support covers snapshot creation, snapshot replication, snapshot restore, and rollover of snapshots to tape or VTL storage.
– SnapVault takes a full PiT snapshot and stores only new and changed data.
– The source and destination volumes (qtrees) must exist before you configure a replication. The volumes may be on the same or separate NetApp devices on the same or separate servers, which may be NetApp virtual machines, and both volumes must be in an online state.
– The source volume must be read-writable and the destination volume must be a data protection type.
– You must configure SnapVault and SnapMirror replication policies on the NetApp devices.
– Validate the replication configuration by performing an initial replication operation.
  This makes the replication policies available as selections in the NetWorker client wizard.
– If the snapshot destination volume is written to, the destination becomes the new source volume and the relationship switches.
– To enable data recovery from NetApp replications, you must specify the NSR_MOUNTPOINT_NAME variable. NetApp devices on Linux operating systems cannot use a temporary mount point.
– In-place recoveries and out-of-place recoveries of an entire directory or save set are not supported. You may recover one or more files, provided the files do not make up the entire contents of a directory.
– A snapshot must be restored to a unique destination volume that is not used for other SnapMirror operations. If the same snapshot exists on the destination volume, an incremental restore is performed and the previous snapshot is overwritten.

Secure HTTPS communication with the Cloud server

NetWorker enables you to use https to securely communicate with the Cloud server. You can configure secure https communications when you configure the cloud device in NetWorker.
You will need to retrieve the SSL certificate for the Cloud server before you create a new device or modify an existing cloud device, and then provide the https address and the certificate information in the Create Device window in NMC. The sections "HTTPS communications with the Cloud server" and "Create and label a Cloud storage device" in
the NetWorker Administration Guide provide details.

Environment variable NSR_CLUSTER_LOGDIR added to change the directory location of NetWorker cluster scripts

Log files for the NetWorker cluster scripts get placed by default in the same directory as the NetWorker scripts (/usr/bin). This is because the location of the standard NetWorker log directory (/nsr/log) may change during a cluster failover.
A new environment variable, NSR_CLUSTER_LOGDIR, allows you to specify a new location to store the NetWorker cluster script log files.

Starting NMC by using an SSH connection

You can now use SSH port forwarding to connect to the NMC server and generate reports from an NMC client. The section "Starting the Console by using an ssh connection" in the NetWorker Administration Guide provides the required steps.

IPv6 support for NDMP backup and recovery

Starting in NetWorker 8.2 SP1, you can use IPv6 for NDMP backup and recovery operations.
By default, NDMP backup and recovery will use IPv6 to create the data connection between the NDMP data server and mover server, when certain requirements are met. The section "Pre-configuration requirements for NDMP data operations" in the NetWorker Administration Guide provides more information.

NetWorker and Data Domain DD Boost integration enhancements

NetWorker 8.2 SP1 introduces the following enhancements to the Data Domain DD Boost integration:
* Support added for DD Boost backup and recovery data transport operations over IPv6 compliant networks with supported Data Domain systems.
* Support of DD Boost over fibre channel (DFC) for NetWorker storage nodes on HP‑UX 11i v3 platforms running IA-64 processors.
* Support of Client Direct backup over DFC connectivity for NetWorker clients on HP‑UX 11i v3 platforms running IA-64 processors.

Renaming a NetWorker server by using nsrclientfix

A new procedure allows you to rename a NetWorker server by modifying the /etc/hosts file to add the new name as an alias and then use nsrclientfix to move the NetWorker server to the new name.
The knowledgebase article 196727, available at http:/support.emc.com, provides full instructions.
