Distributed segment processing

Distributed segment processing uses the DD Boost library on the database server and the DD software on DD Replicator. The Microsoft application agent loads the DD Boost library during backup and restore operations.

Distributed segment processing allows the Microsoft application agent to perform parts of the deduplication process, which avoids sending duplicate data to the DD system that you configured as a storage server.

The distributed segment processing feature provides the following benefits:

• Increases throughput because the DD Boost library sends only unique data to the DD system. The throughput improvements depend on the redundant nature of the data that you back up, the overall workload on the database server, and the database server capability. In general, greater throughput is attained with higher redundancy, greater database server workload, and greater database server capability.
• Decreases network bandwidth requirements by sending the unique data to the DD system through the network.

Manage distributed segment processing by using the ddboost command options. Use distributed segment processing if the network connection is 1 Gb Ethernet. Configuring distributed segment processing provides information on how to configure the distributed segment processing.

Distributed segment processing supports the following modes of operation for sending backup data to a DD system:

• Distributed segment processing enabled
• Distributed segment processing disabled

Set the operation mode on the DD system. The Microsoft application agent negotiates with the DD system for the current setting of the option and accordingly performs backups.
