To support the DD Boost technology, Veeam Backup & Replication leverages the following Dell EMC Data Domain components:
- DD Boost library. The DD Boost library is a component of the Dell EMC Data Domain system. The DD Boost library is embedded into the Veeam Data Mover Service setup. When you add a Microsoft Windows server to the backup infrastructure, the DD Boost Library is automatically installed on the added server together with the Data Mover Service.
- DD Boost server. The DD Boost server is a target-side component running on the OS of the Dell EMC Data Domain storage system.
To communicate with Dell EMC Data Domain, Veeam Backup & Replication uses the DD Boost library deployed on a gateway server. The gateway server is a backup infrastructure component that “bridges” the backup server and Dell EMC Data Domain storage system. The gateway server must meet the following requirements:
- The server must run Microsoft Windows OS.
- The server must be added to the backup infrastructure.
- The server must have access to the backup server and Dell EMC Data Domain appliance.
You define what gateway server to use when you assign a backup repository role to Dell EMC Data Domain. You can define the gateway server explicitly or instruct Veeam Backup & Replication to select it automatically.
For Dell EMC Data Domain storage systems working over Fibre Channel, you must explicitly define the gateway server that will communicate with Dell EMC Data Domain. As a gateway server, you must use a Microsoft Windows server that is added to the backup infrastructure and has access to Dell EMC Data Domain over Fibre Channel.
