To support the EMC DD Boost technology, Veeam Backup & Replication leverages two EMC Data Domain components:
- DD Boost library. The DD Boost library is a component of the 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 EMC Data Domain storage system.
To communicate with 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 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 EMC Data Domain appliance.
You define what gateway server to use when you assign a backup repository role to EMC Data Domain. You can define the gateway server explicitly or instruct Veeam Backup & Replication to select it automatically.
For EMC Data Domain storage systems working over Fibre Channel, you must explicitly define the gateway server that will communicate with 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 EMC Data Domain over Fibre Channel.
