How do I configure Legato's NetWorker for Mirapoint NDMP selective restore from an image?
Note: Before reading this article, Mirapoint highly recommends reading the latest version of the Mirapoint Backup and Restore Guide.
This document describes how to modify your existing Legato NetWorker (version 7.1) DMA configuration and Mirapoint NDMP backup setup to allow for selective restore from an image.
If you are running NetWorker version 7.1.2 on a Solaris workstation, install the 64-bit package. Legato's 32-bit version does not operate correctly when working with NDMP file histories. Versions other than the 64-bit package can "hang" when attempting to do a recovery. If you are running NetWorker's 32-bit package you need Legato's patch, or you have to uninstall it and install the 64-bit package.
Legato's Windows 2000 version also fails without their patch. Contact Legato directly for more information on running either the Solaris 32 bit package or the Windows 2000 version.
Your Mirapoint appliance must be equipped with 3.6 or higher operating system.
This procedure applies to Unix systems.
For more information on how to configure the NetWorker DMA to work with a Mirapoint appliance, see:
- Configuring Legato NetWorker for Mirapoint NDMP Backup
- Using Legato NetWorker to Perform an NDMP Selective Restore From Image
For more information on configuring and supporting Legato's NDMP, refer to the Legato NetWorker Administrator's Guide provided with your Legato software.
Overview of the Configuration Process
Before using selective restore, you might need to modify your basic NetWorker configuration so that it produces a history file each time you perform a backup.
Prior to release 3.6, Mirapoint required the history setting be no (n). As of 3.6, the history file settings must be yes (y).
Setting the DMA Type in the Mirapoint Software
As of Release 3.6, you can add the specific NDMP DMA you are using to the Mirapoint appliance configuration. Changing your DMA setting allows the Mirapoint NDMP service to adjust itself to the requirements of each approved DMA.
To set the NDMP DMA, do the following:
2. Type the following CLI command:
Modifying Your NetWorker DMA Setup
This procedure assumes you are using a Solaris workstation.
Your Mirapoint client configuration in the Legato DMA must be modified so that it produces a history file. Do the following:
