Configuring and Using Rapid Data Access with
NetVault Backup and with vRanger
Overview
Rapid Data Access (RDA) with NetVault Backup (NVBU) and with vRanger provides the logical disk interface that can be
used with network storage devices. The Dell DR Series system requires a DR Rapid plug-in to integrate its data storage
operations with NVBU and vRanger. The plug-in is installed by default on the NVBU and vRanger servers and the Dell DR
Series system when the latest software updates are installed. Using the DR Rapid plug-in, the DMAs can take full
advantage of key DR Series system features like replication and data deduplication.
When DR Rapid is used with the DR Series system, it offers the following benefits:
• RDA with NVBU and RDA with vRanger protocols provide faster and improved data transfers:
– Focus is on backups with minimal overhead
– Accommodates larger data transfer sizes
– Provides throughput that is better than CIFS or NFS
• DR Rapid and data management application (DMA) integration:
– DMA-to-media server software communication
– DR Series system storage capabilities can be used without extensive changes to DMAs
– Backup and replication operations are simplified by using built-in DMA policies
• DR Series system and DR Rapid ports and write operations:
– Control channel uses TCP port 10011
– Data channel uses TCP port 11000
– Optimized write operations enable client-side deduplication
• Replication operations between DR Series systems:
– No configuration is required on the source or target DR Series system
– Replication is file-based, not container-based
– Replication is triggered by DMA optimized duplication operation
– DR Series system transfers the data file (not the media server)
– After duplication completes, DR Series system notifies DMA to update its catalog (acknowledging the second
backup). This makes the DMA aware of the replication location. Restores from either the source or replication
target can be used directly from the DMA.
– Supports different retention policies between source and replica
– Replication is set up in the DMA itself, not the DR Series system
