Data Protector 10.03, which was released in March, introduced many enhancements that make Data Protector backup and recovery software easier to deploy and manage. One of these features is the out-of-the-box support for HPE StoreOnce Cloud Bank capability which we described in this recent blog. Another enhancement is the fact that Data Protector 10.03 is a direct, one-step upgrade for customers currently on Data Protector 8.x, 9.x or 10.x.   

Today we will do a deep dive into another key Data Protector 10.03 capability, the support for NetApp NDMP 3-Way backup to HPE StoreOnce Catalyst and to Data Protector File Libraries.  Watch this short video with a demo of this feature. This 3-way support, also known as remote NDMP, removes the requirement to have an NDMP backup target attached directly to the NetApp Filer. It also allows for the centralizing of StoreOnce Catalyst backup via common media server(s) with deduplication enabled for all workloads. Note: File Library support is also available for customers without a StoreOnce backup appliance.

Data Protector NetApp 3-way NDMP simplifies NDMP backup configuration and management by eliminating the need to attach, configure and manage backup targets on each NetApp filer. This is accomplished because the backup data transfer is managed by the Data Protector NDMP media agent instead of the NetApp Filer itself. This NetApp 3-way NDMP support for StoreOnce Catalyst also removes the requirement for StoreOnce VTL targets.

What is NDMP?

NDMP, or Network Data Management Protocol, is a protocol used to transport backup data between network attached storage (NAS) appliances and backup devices. NDMP uses a client server model where the backup software initiates the backup process while the NAS appliance performs the actual backup operations.

The NDMP protocol supports two data protection mechanisms: 2-way – and 3-way. In a 2-way NDMP configuration, the NAS filer is connected directly to a backup device such as a tape library and the backup software instructs the filer to perform a backup. The filer itself manages the data transfer directly to the backup medium.Data Protector 2-way NDMP.png

In a 3-way NDMP configuration, all backup data is sent from the NAS filer to the backup software media agent over the network. The media agent then sends the backup data to the appropriate backup device.

Data Protector has traditionally provided support for 2-way NDMP configurations for NAS appliances from several vendors including NetApp, EMC, HPE, Hitachi and Oracle. With Data Protector 10.03, NDMP support has been extended to provide 3-way support for NetApp filers with StoreOnce Catalyst and File Library targets. 3-way support for additional NAS appliances as well as additional targets will be added in future releases.

How does Micro Focus Data Protector Work with NetApp 3-Way NDMP to HPE StoreOnce?

Data Protector integrates with NDMP through the Data Protector NDMP library and the NDMP Media Agent. The Data Protector NDMP library channels communication between the Data Protector Session Manager, and, through the NDMP interfaces, the NDMP appliance.

Here are the steps to configure the Data Protector NetApp 3-way NDMP server integration with a StoreOnce Catalyst target:

  1. Import the NetApp appliance into the Data Protector cell as an NDMP ServerNet App Appliance into Data Protector.png



2. Deploy the NDMP Media Agent to the appropriate media server(s)


3. Create a StoreOnce Catalyst NDMP target deviceStoreOnce Calatyst.png



  • Device Type = Backup to Disk
  • Interface Type = StoreOnce Backup System (NDMP)


4. Create a filesystem backup specification for the NetApp applianceNet App backup speficiation.png


  • Backup Type = Data Mover Backup
  • Sub Type = NDMP – NetApp
