Setting Up the Dell DR Series System as an RDA or VTL Backup Target for Dell NetVault Backup

2.2

Configuring transport modes for NetVault Backup

There are two transport modes for backing up data over RDA: Optimized / Dedup and Passthrough.

Optimized backup does source side dedupe on the NVBU clients. The Passthrough mode does target side

dedupe on the DR Series system.

The default mode for each client is decided based on the number of CPU cores in the client machine and

whether the architecture is 32-bit or 64-bit. In general, there is no need to change the mode. In the event you

want to change the mode, it can be done by setting the RDA mode in the DR Series system command prompt

or through the GUI.

2.2.1

Setting the mode using the CLI

Open an ssh session to the DR Series system and run the following command:

rda --update_client --name <hostname of client> --mode <dedupe/passthrough>

2.2.2

Setting the mode using the GUI

In the DR Series system GUI, follow the steps:

1.

Navigate to the Clients page, and select the

RDA

tab. The list of clients that have active connections is

shown.

2.

Select the client for which you want to change the mode.

3.

On the top right side of the page, click the

Update Client

link.

4.

Select the required mode from the drop down menu, and click

Submit
