Data Domain System prerequisites

Before adding a Data Domain system to a NetVault Backup Server, verify that the following requirements are met:

Install DD Boost license on the Data Domain System: To use a Data Domain system for backups and restores, install the required DD Boost license and enable DD Boost on the Data Domain systems.
Create a DD Boost user account: On the Data Domain system, create a DD Boost user account that can be used to log on to the device for backups and restores.
Configure the required DD Boost features: On the Data Domain system, configure the features that you want to use. For more information about enabling and configuring DD Boost features, see the DD Boost section in the DD OS Administration Guide.
Open the required firewall ports: To perform DD Boost backups and replication across a firewall, open the following ports on the Data Domain system:
Install Microsoft Visual C++ 2005 SP1 Redistributable Package on Windows: Install the Microsoft Visual C++ 2005 SP1 Redistributable Package on Windows-based NetVault Backup Server. This requirement applies to all supported Windows platforms. The DD Boost library fails to load if you do not install this package on Windows.
Configure network time-outs: Backup and restore jobs often take a long time to complete. Although the DD Boost Library can recover from temporary network interruptions, the operating system on the data protection application system might terminate a job prematurely if the data protection application time-outs are set too low. To avoid this, Data Domain recommends setting time-outs to at least 30 minutes (1800 seconds).

Adding a Data Domain System

To use a Data Domain system for backups and restores, you must first add the device to the NetVault Backup Server. You can use the configuration wizard to add and configure this device.

1
In the Navigation pane, click Guided Configuration, and then on the NetVault Configuration Wizard page, click Add Storage Devices.
In the Navigation pane, click Manage Devices, and then click Add Device.
2
On the Add Storage Devices page, select the EMC DataDomain Boost Device option, and click Next.
3
On the Add EMC DDBoost Storage page, provide the following details.

Network name/IP address

Type the Fully Qualified Domain Name (FQDN) or IP address of the Data Domain system.

If the server is unable to resolve the host name, it fails to add the device.

Username

Specify a DD Boost user account that can be used to log on to the device for backups and restores. Verify that the user account is created on the Data Domain system before you add the device to the NetVault Backup Server.

Password

Type the password for the user account.

LSU

Type the name of the Logical Storage Unit (LSU). If the specified LSU does not exist on the Data Domain system, NetVault Backup automatically creates it when you add the device to the server. You can configure multiple LSUs on a single Data Domain system.

Each Data Domain system added to NetVault Backup represents an LSU.

Block size

Type or select the block size for data transfers. The block size is specified in KiB. The default block size is 128 KiB.

Stream Limit

The default value for this setting is 32 streams. This setting applies to all NetVault Backup Servers to which the container is added. If the number of data streams exceeds the defined limit for the container, the Media Manager reports an error (“Device has too many streams”).

You can set the soft stream limit to any value between 1 and 256.

If the container is added to more than one NetVault Backup Server, set the same soft stream limit on all servers.

Force add

If the device is already added to another NetVault Backup Server with the same name, select the Force add check box. This option can be useful if you have performed a disaster recovery to rebuild the NetVault Backup Server.

Click Next to add the device.

NetVault Backup writes the data transfer statistics for Data Domain Systems to the stats.stnz file. The nvstatsmngr process uses this file and requires that it is regularly updated. However, frequent updates can have a significant performance impact on the system. By default, NetVault Backup updates the file after every 5 seconds or 10 blocks of data transfer. You can change this default setting from the Change Settings page. For more information, see Configuring transfer update settings for foreign RAS devices.

DD Boost commands

This section provides a brief description of the DD Boost commands that you can use to manage the DD Boost features on a Data Domain system. For a detailed description of these commands, see the DD Boost section in the DD OS Administration Guide. For information about configuring DD Boost from the graphical-user interface-based Enterprise Manager, see the DD OS Administration Guide.

This command is equivalent to issuing the ddboost ifgroup disable command followed by multiple ddboost ifgroup del interface ipaddr commands.
