This version was released like 2 weeks ago, but it took EMC sometime to release this information to public. It is here now!
It is release 188.8.131.52, Build 614.
New features and changes in NetWorker 9.0 SP1
The NetWorker 9.0 SP1 software contains the following new features and enhancements, such as:
Enhancements to Data Domain support
NetWorker 9.0.1 includes the following Data Domain related enhancements:
Improved performance of NetWorker Clone Controlled Replication (CCR) for Data Domain due to Automated Multi-streaming
The Automated Multi-streaming (AMS) feature improves cloning performance for large save sets when you use high bandwidth networks. Previously when you replicated save sets between two Data Domain devices on different machines, the replication process used to take longer in NetWorker. AMS significantly speeds up replication between DDRs by splitting up large files (files whose sizes are roughly greater than 3.5 GB) into multiple smaller 2 GB slices, replicating the slices individually, and finally re-creating the original large file on the destination DDR using those slices.
NetWorker 8.2.3 and NetWorker 9.0.1 and later feature enhancements to clone controlled replication (CCR), also known as DD to DD Managed File Replication. Also, enhancements to load balancing so that the load (save sets to clone) is spread evenly across the multithreaded nsrclone process were implemented. By default, the AMS feature is disabled.
You can turn on the feature by changing the command to ams_enabled=yes.
Support for DD Boost Fibre Channel on Solaris 10 and 11
DD Boost Fibre Channel now supports Solaris versions 10 and 11 for the File System Client.
DDOS version 5.7.x high availability failover capabilities
NetWorker 9.0.1 allows you to make use of the Data Domain failover capabilities available in DDOS 5.7.x for both DD Boost and non-Boost devices, introducing the following enhancements:
- View status information and reports from NMC’s Monitoring window.
- In the result of a failover, perform an unscheduled shutdown of the primary Data Domain device to ensure that NetWorker operations in progress (including backup, recovery and configuration options) are not interrupted.
If you run an inquire during a Data Domain failover, the VTL output does not display.
There is, however, no impact to the backup.
Starting in NetWorker 9.0.1, NDMP now supports:
- Isilon Multi-Streaming
- Muting verbose log messages for successfully recovered files
- Token based backup for Hitachi NAS
Added storage array support for snapshot management
NetWorker Snapshot Management now supports the following storage arrays:
- EMC ProtectPoint for VMAX3
- EMC ProtectPoint for RecoverPoint
- EMC XtremIO
A detailed description of configuring ProtectPoint on RecoverPoint with XtremIO and configuring Snapshots on XtremIO arrays is available in the EMC NetWorker Snapshot Management Integration Guide.
Support for CloudBoost devices
The NetWorker 9.0.1 release supports the use of a CloudBoost appliance to backup and clone data.
CloudBoost Virtual appliance support on Amazon Web Services
NetWorker 9.0.1 introduces support for ClouldBoost Virtual appliances on Amazon Web Services. By utilizing a virtual machine that is Amazon Machine Image (AMI) compatible, The CloudBoost Virtual appliance supports both long-term retention and backup to cloud, allowing you to benefit from Amazon’s Simple Storage Service (S3) deduplication.
Limit the number of overall NetWorker sessions to the Amazon Web Services S3 bucket to 100 streams. When you use more than 100 streams, intermittent backup failures occur with an error message similar to "503 slow down".
Jobs database changes
Improvements to the jobsdb were made inNetWorker 9.0.1, and the format of the jobsdb changed. Also, the default retention period of jobsdb is now 72 hours. You can modify the retention period by editing the variable Jobsdb retention in hours.
Previous versions of the jobsdb are not compatible with NetWorker 9.0.1 and the update process does not migrate the jobsdb data. When you update from a previous release to NetWorker 9.0.1, the updating process renames the jobsdb and the NetWorker server uses a new database.
After you update the NetWorker server, all policy, workflow, and action resources will report a status of never run. This status also displays after a workflow has expired.
VMware Virtual Volumes (vVol) Support for VMAX3 and UNITY storage systems
Networker 9.0.1 allows backup and restore of virtual machines that are running on vVol datastores.
NetWorker REST API
The NetWorker REST API is an interface that allows you to access the NetWorker data protection service and to build client applications that automate NetWorker operations.
The NetWorker REST API Getting Started Guide describes how to use the NetWorker REST API, and the NetWorker REST API Reference Guide provides a full description of the API resources.
Highly-available NetWorker server support
The NetWorker 9.0.1 release supports a highly-available NetWorker server on supported Windows and RHEL operating systems.
