Installing and configuring DDBoost
• Configuring the Data Domain system
Installing DDBoost
NOTE: Complete descriptions of commands used in this guide are provided in the EMC Data Domain Operating System Command Reference Guide.
The overall steps for installing DDBoost are as follows:
1 Obtain the license required to enable DDBoost on the Data Domain system; purchase a DDBoost license key from EMC.
▪ The DDBoost license allows you to back up and restore data.
▪ A separate replication license enables you to perform replication. You must obtain a replication license for both the source and destination Data Domain systems.
2 Enable and configure DDBoost on the Data Domain system.
At a minimum, configuration includes specifying the DDBoost user name and password.
3 Install vRanger, which contains the DDBoost Libraries.
The EMC� Data Domain� system as it is initially configured does not work through a firewall. If you need the Data Domain system to work in the presence of a firewall, contact your network support provider.
The following ports must be open in a firewall for EMC� Data Domain� Boost (DDBoost�) backups and replication to work:
• TCP 2049 (Network File System [NFS])
• TCP xxx (select a random port for NFS mountd)
Enabling DDBoost on a Data Domain system
Every EMC� Data Domain� system that is enabled for EMC� Data Domain� Boost (DDBoost�) must have a unique name. You can use the Data Domain system’s DNS name, which is always unique.
1 On the Data Domain system, log in as an administrative user.
2 Verify that the file system is enabled and running by entering:
The file system is enabled and running.
3 Add the DDBoost license using the license key that Data Domain provided:
License "ABCE-BCDA-CDAB-DABC" added.
4 Set the DDBoost user by entering:
# ddboost set user-name ddboost-user
Configuring the Data Domain system
This topic describes tasks and commands for configuring the EMC� Data Domain� system.
• Creating a DDBoost user name
• Configuring distributed segment processing
• Configuring Advanced Load Balancing and Link Failover
Creating a DDBoost user name
An EMC� Data Domain� Boost (DDBoost�) user is an EMC� Data Domain� user. Before setting the DDBoost user access, the username and password must have already been set up on the Data Domain system. vRanger uses the DDBoost user account to connect to the DDBoost repository.
When DDBoost is enabled, a Data Domain OS administrative user can set or change to another DDBoost user. Only one DDBoost user can operate DDBoost at a time.
To set or modify the DDBoost user name:
1 In the DDBoost overview pane located under the Data Management tab, click Add or Modify in the DDBoost User area.
The Set or Modify DDBoost User Name dialog box appears.
▪ To add a user, click the User Name button.
a Enter the user name in the DDBoost User Name field.
The user must be configured in the backup application to connect to the Data Domain system.
b Enter the password twice in the text fields.
c Select the privilege level for this user: admin or user.
▪ To switch to a user that has already been added, click the Existing User button, and select the user name from the drop-down list.
The EMC� Data Domain� system exposes pre-made disk volumes called storage units to an EMC� Data Domain� Boost (DDBoost�)-enabled backup server. Each Storage Unit is a top-level subdirectory of the /data/col1 directory; there is no hierarchy among Storage Units. When used with vRanger, a DDBoost repository is configured at the Storage Unit level, meaning each DDBoost repository in vRanger equates to exactly one Storage Unit.
NOTE: You may also create a Storage Unit from the vRanger UI during the DDBoost repository configuration, or by using the EMC Data Domain Enterprise Manager web console.
1 To create a storage unit on the Data Domain system, enter:
# ddboost storage-unit create storage-unit_name
IMPORTANT: Each storage unit name must be unique. For devices running Data Domain OS 5.2 and later, the supported characters are alphanumeric characters and ~!@#$^_+`-={}[],.
2 Repeat the previous step for each DDBoost-enabled Data Domain system.
Configuring distributed segment processing
The distributed segment processing option is configured on the EMC� Data Domain� system and applies to all the backup servers and the EMC� Data Domain� Boost (DDBoost�) Libraries installed on them. For more information, see Distributed segment processing.
The option can be configured using the following command:
# ddboost option set distributed-segment-processing {enabled | disabled}
NOTE: Enabling or disabling the distributed segment processing option does not require a restart of the Data Domain file system.
Distributed segment processing is supported with DDBoost Library version 2.2 or later communicating with a Data Domain system that is running Data Domain OS 5.2 or later.
Distributed segment processing is enabled by default on a system initially installed with Data Domain OS 5.2. If a system is upgraded from Data Domain OS 5.0.x to Data Domain OS 5.2 or later, distributed segment processing is left in its previous state.
Configuring Advanced Load Balancing and Link Failover
If an interface group is configured, when the EMC� Data Domain� system receives data from the backup server clients, the data transfer is load balanced and distributed as separate jobs on the private network, providing higher input and output throughput, especially for customers who use multiple 1 GbE connections.
Create an interface group on the Data Domain system by adding existing interfaces to the group and registering the Data Domain system with vRanger, as described in the following steps.
1 Verify that the interfaces have been created with the net command.
2 Add the interfaces into the group.
# ddboost ifgroup add interface 192.168.1.1
# ddboost ifgroup add interface 192.168.1.2
# ddboost ifgroup add interface 192.168.1.3
# ddboost ifgroup add interface 192.168.1.4
3 Select one interface on the Data Domain system to register with vRanger.
Quest recommends that you create a failover-aggregated interface and register that interface with vRanger.
It is not mandatory to have one of the interfaces in the ifgroup registered with vRanger. An interface that is not part of the ifgroup can also be used to register with vRanger.
NOTE: EMC recommends that you register the interface with a resolvable name using DNS or any other name resolution mechanism.
The interface registered with vRanger is used by vRanger and the DDBoost Library to communicate with the Data Domain system. If this interface is not available, backups to that Data Domain system are not possible.
4 Enable the feature on the Data Domain system:
5 Verify the configuration of the Data Domain system:
After the interface group is set up, you can add or delete interfaces from the group. You can manage Advanced Load Balancing and Link Failover — an interface group — by using the ddboost ifgroup command or from the Enterprise Manager Data Management > DD Boost view. For more information, see the EMC Data Domain Operating System Administration Guide.
With EMC� Data Domain� Boost (DDBoost�), vRanger can control replication between multiple EMC� Data Domain� systems and provide backup administrators with a single point of management for tracking all backups and duplicate copies. This configuration lets you efficiently create disaster recovery (DR) copies of your backups over the WAN, and track all the copies using the vRanger catalog for easy recovery.
When using EMC� Data Domain� Boost (DDBoost�) with vRanger, replication is configured through the vRanger interface. For instructions on enabling replication, see Configuring repository replication.
Enabling low-bandwidth optimization
To enable the low-bandwidth option, enter:
# ddboost file-replication option set low-bw-optim enabled
Low bandwidth optimization enabled for replication.
Enabling or disabling the low-bandwidth optimization option does not require a restart of the EMC� Data Domain� file system. After enabling low-bandwidth optimization, however, you need to run a full cleaning cycle on the Data Domain system for it to be effective.
Low-bandwidth optimization can be monitored and managed with the command ddboost file replication or from the Enterprise Manager Data Management > DD Boost view. For more information, see the EMC Data Domain Operating System Administration Guide.
No configuration changes are necessary on the backup server as this feature is transparent to the data protection applications.
• Enabling this feature takes additional resources — CPU and memory — on the Data Domain system; Quest recommends that you use this option only when replication is being done over low-bandwidth networks with less than 6 Mbps aggregate bandwidth.
• For more information on this feature, see the EMC Data Domain Operating System Administration Guide.
• The low-bandwidth option for replication is supported only for standalone Data Domain systems.
Enabling encrypted file replication
To enable the encrypted file-replication option, enter:
# ddboost file-replication option set encryption enabled
The output indicates that the encryption you requested was enabled.
For more information, see the command ddboost file-replication.
No configuration changes are necessary on the backup server as this feature is transparent to the data protection application. Turning on this feature takes additional resources — CPU and memory — on an EMC� Data Domain� system.
• Enabling or disabling the encrypted file replication option does not require a restart of the Data Domain file system.
• For more information on this feature, see the EMC Data Domain Operating System Administration Guide.

It is not mandatory to have one of the interfaces in the ifgroup registered with vRanger. An interface that is not part of the ifgroup can also be used to register with vRanger.
NOTE: EMC recommends that you register the interface with a resolvable name using DNS or any other name resolution mechanism.
The interface registered with vRanger is used by vRanger and the DDBoost Library to communicate with the Data Domain system. If this interface is not available, backups to that Data Domain system are not possible.
4 Enable the feature on the Data Domain system:
5 Verify the configuration of the Data Domain system:
After the interface group is set up, you can add or delete interfaces from the group. You can manage Advanced Load Balancing and Link Failover — an interface group — by using the ddboost ifgroup command or from the Enterprise Manager Data Management > DD Boost view. For more information, see the EMC Data Domain Operating System Administration Guide.
With EMC� Data Domain� Boost (DDBoost�), vRanger can control replication between multiple EMC� Data Domain� systems and provide backup administrators with a single point of management for tracking all backups and duplicate copies. This configuration lets you efficiently create disaster recovery (DR) copies of your backups over the WAN, and track all the copies using the vRanger catalog for easy recovery.
When using EMC� Data Domain� Boost (DDBoost�) with vRanger, replication is configured through the vRanger interface. For instructions on enabling replication, see Configuring repository replication.
Enabling low-bandwidth optimization
To enable the low-bandwidth option, enter:
# ddboost file-replication option set low-bw-optim enabled
Low bandwidth optimization enabled for replication.
Enabling or disabling the low-bandwidth optimization option does not require a restart of the EMC� Data Domain� file system. After enabling low-bandwidth optimization, however, you need to run a full cleaning cycle on the Data Domain system for it to be effective.
Low-bandwidth optimization can be monitored and managed with the command ddboost file replication or from the Enterprise Manager Data Management > DD Boost view. For more information, see the EMC Data Domain Operating System Administration Guide.
No configuration changes are necessary on the backup server as this feature is transparent to the data protection applications.
• Enabling this feature takes additional resources — CPU and memory — on the Data Domain system; Quest recommends that you use this option only when replication is being done over low-bandwidth networks with less than 6 Mbps aggregate bandwidth.
• For more information on this feature, see the EMC Data Domain Operating System Administration Guide.
• The low-bandwidth option for replication is supported only for standalone Data Domain systems.
Enabling encrypted file replication
To enable the encrypted file-replication option, enter:
# ddboost file-replication option set encryption enabled
The output indicates that the encryption you requested was enabled.
For more information, see the command ddboost file-replication.
No configuration changes are necessary on the backup server as this feature is transparent to the data protection application. Turning on this feature takes additional resources — CPU and memory — on an EMC� Data Domain� system.
• Enabling or disabling the encrypted file replication option does not require a restart of the Data Domain file system.
• For more information on this feature, see the EMC Data Domain Operating System Administration Guide.
