Data Domain Boosts Data Backup with Pre-Processing

EMC's Data Domain says that DD Boost, installed on a media server and integrated with either Symantec NetBackup or Backup Exec, can pre-processes backup data on a media server to increase deduplication speed by up to 50 per cent. According to this report on The Register, EMC will add DD Boost support to its own NetWorker backup software.

"The software is installed on a media server and is integrated with either Symantec NetBackup or Backup Exec. It is a library and is used to identify segments in incoming data. The segment IDs are checked with the connected Data Domain array which says which ones are new. These are compressed on the media server and sent over the wire, reducing both local network traffic and the overall transfer time for the data."
