What Is EMC DD Boost and How Does It Speed Up Enterprise Backups?
This article introduces EMC's DD Boost—a proprietary protocol for Data Domain that improves backup efficiency, lists the backup applications that support it, explains required TCP ports and storage unit setup, and outlines its key features such as distributed segment processing and load balancing.
EMC DD Boost is a proprietary protocol for Data Domain that provides more efficient data transfer than CIFS or NFS, allowing backup software to standardize and centrally manage Data Domain systems.
Supported Backup Software
EMC Avamar (VMware virtual backup, both software and appliance)
EMC NetWorker
Oracle Recovery Manager (RMAN)
Quest vRangerPro (acquired by Dell; physical backup NetVault, virtual vRanger/vReplicater)
Symantec Backup Exec
Symantec NetBackup
EMC Avamar and EMC NetWorker include DD Boost plugins by default; other third‑party products require a separate DD Boost plugin and a DD Boost license key to enable the feature.
Enabling DD Boost
To activate DD Boost you must first enter the DD Boost serial number and open the following TCP ports on the backup client:
TCP 2049 (NFS)
TCP 2051 (replication)
TCP 111 (NFS portmapper)
When DD Boost is enabled, the backup client stores data in a “storage unit” on the Data Domain appliance, which must be created manually beforehand.
Key DD Boost Functions
Distributed Segment Processing (DSP)
Managed File Replication
Advanced Load Balancing and Link Failover
Virtual Synthetics
The article notes that future sections will detail each of these functions in depth.
