Enabling replication

Enabling replication

When using EMC® Data Domain® Boost (DD Boost™) with vRanger, replication is configured through the vRanger interface. For instructions on enabling replication, see Configuring repository replication.

Enabling low-bandwidth optimization

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.

Notes:

•	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

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.

Notes:

•	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.

vRanger system requirements

Before installing vRanger and EMC® Data Domain® Boost (DD Boost™), ensure that you read and understand the requirements and limitations of both products. The following topics summarize the system requirements for vRanger.

IMPORTANT: The following information is a summary. Before implementing vRanger, review the Quest vRanger Installation/Upgrade Guide.

For vRanger and DD Boost to integrate, you must use the following versions:

•

vRanger

•	At least one EMC® Data Domain® device running:

▪	Data Domain OS 5.7 — requires vRanger 7.3 or later

▪	Data Domain OS 6.0— requires vRanger 7.6.3 or later
