4 Setting Up the Dell™ DR Series System on Symantec NetBackup to Use Backup Acceleration | May 2014
Executive summary
This paper provides information about how to set up the Dell DR Series system to run backup acceleration on
NetBackup (NBU). This document is a quick reference guide and does not include all DR Series system deployment best
practices.
For additional data management application (DMA) best practice whitepapers, see the DR Series system documentation

Note: The DR Series system and NetBackup screenshots used in this document may vary slightly, depending on the
DR Series system firmware version and NetBackup version used.
Terminology
• Backup Accelerator: Inline synthetic creation during backup.
•
Dedupe backup: In this mode, deduplication is done on the client and then the deduplicated packets are sent to the
DR Series system.
• Optimized duplication: Optimized duplication allows disk-based backups to be replicated between devices under
NBU control. In other words, Optimized duplication enables deduplicated data to be copied directly from one
OpenStorage (OST) device to another OST device from the same vendor.
• Passthrough backup:
In this mode, deduplication is done on the DR Series system after data is transferred from the
client.
•
RDA : Rapid Data Access, which is Dell’s proprietary technology for faster data access.
• Synthetic backup:
A synthetic backup is identical to a regular full backup in terms of data, but it is created when data
is collected from a previous, older full backup and assembled with subsequent incremental backups.
