# Data Domain Boost Storage Library

Commvault Data Domain Boost Storage Library feature is an integration between the Commvault data protection software and the Dell EMC® Data Domain® and PowerProtect DD® deduplication storage systems. Commvault is a Dell DD Boost ecosystem partner and has incorporated the DD Boost SDK into the Commvault platform, which now allows advanced levels of integration and feature support with no additional software or plug-ins required.

When using the Commvault Data Domain Boost Storage Library feature, the software makes a direct connection to the Dell EMC® Data Domain® device through the SDK to move data directly and securely without the need to expose mount points or use network shares. This allows more control over the data operations leading to enhanced resiliency and more efficient data transfer during backups and restores. SDK integration also provides access to the full set of Dell DD Boost APIs and features.

Important

For VSA synthetic full backups and restores using DD Boost media, enabling the VSACreateSeparateAFForEachDisk setting improves performance. For more information, see Settings.

After enabling the setting, the next incremental backup job is automatically converted to a full backup. This job and all subsequent jobs run with the feature enabled.

If a synthetic full backup is run immediately after enabling the setting, it runs without the feature enabled. The feature becomes active only after a full backup job completes.

This feature is enabled by default on newly installed CommServe systems.
