New Features and Changes in NetWorker 9.1

The following topics provide details on the new features and changes that are available starting with the release of Networker 9.1 that is covered in the Release Notes

NetWorker VMware Protection with the vProxy appliance

NetWorker 9.1 provides you with the ability to perform virtual machine protection and recovery by using NetWorker VMware Protection with the vProxy appliance, also known as NVP. With NVP, NetWorker directly manages the vProxy appliances without the use of an external node for proxy management.

NVP has the following benefits:

  • Uses standalone data mover proxy appliances, or vProxy appliances to backup and restore virtual machines that run in a virtualized infrastructure.
  • NetWorker directly manages the vProxy appliances without the use of an external node for proxy management and load balancing.
  • Stores the virtual machine backups as raw VMDKs on the Data Domain device, which reduces overhead. NetWorker does not convert the backup to any backup streaming formats.
  • Provides the ability to clone virtual machine backups. When you use streaming devices such as tape, NetWorker converts the save set directories format (SSDF) to Common Data Storage Format (CDSF) during a clone operation, and converts back to SSDF on Data Domain for recovery from streaming devices.
  • Provides user interfaces to perform image-level recovery by using the NMC Recovery wizard or the VM Backup and Recovery plug-in in the vSphere Web Client, and file-level recovery by using the NMC Recovery wizard or the EMC Data Protection Restore Client.

SmartSnap for centralized snapshot management

NetWorker 9.1 allows you to backup and restore VMAX devices using a device worldwide name (WWN).

The SmartSnap feature enables centralized snapshot management and snapshot support for operating system platforms where traditional NetWorker Snapshot Management (NSM) is not supported. The backup component of this feature is supported by the NMC Client Configuration wizard when you select the SmartSnap option from the Available applications and select the Snapshot checkbox. Restore is supported at the array device level.

Rollback to an alternate location

NetWorker 9.1 allows you to perform an array level restore (rollback) of a snapshot to an alternate set of devices.

You can pre-select the device. The devices should be of the same size or larger than the original source devices and should be visible to an alternate host. You must create the same file systems that were on the source devices.


Highly Available Data Domain system support

NetWorker 9.1 supports highly available Data Domain systems. You can add a highly available Data Domain system by creating a new host in NMC.

Data Domain Cloud Tier device support

NetWorker 9.1 provides the ability to clone save sets to a Data Domain Cloud Tier device. Data from the Cloud Tier devices are cloned to a supported Public Cloud provider.

NetWorker support in the vRealize Data Protection Extension

The EMC vRealize Data Protection Extension version 4.0 features support for data protection (backup and recovery operations) on NetWorker 9.1. In previous releases, data protection was only available for Avamar systems.

vRealize data protection for NetWorker consists of the following:

  • Image level data protection, which backups virtual machines at the disk level.
  • Image level recovery, to recover virtual machines to the original location or a new location.
  • File level restore using the EMC Data Protection Restore Client.

The following limitations apply to NetWorker data protection support:

  • Restore from a deleted virtual machine is not supported.
  • Networker does not support multi-tenancy for VMware data protection. Multitenancy can be supported with vRA by assigning/dedicating one Networker instance per tenant.

Direct update from NetWorker 8.1 to NetWorker 9.1

A direct update to NetWorker 9.1 from the NetWorker 8.1 release is now supported.
