HP Dynamic Deduplication - achieving a 50:1 ratio
In June 2008, HP introduced two additional products to the HP StorageWorks D2D Backup System Family, the 1U rack-mountable D2D2500 and the 2U rack-mountable D2D4000. Both new products feature Dynamic deduplication based on an HP-patented deduplication algorithm that packs up to 50 times more backup data into the same disk footprint - giving you a better chance of restoring your users, lost data from exactly the point they need it. And because fast restores of lost files are the hallmark of disk-based backup, your users are getting what they want when they want it. In any organization today, time is money, so restoring data and getting people back to work as quickly as possible saves money... and can save your reputation too.
This paper explains how Dynamic deduplication works and also establishes how a 50:1 deduplication ratio may be achieved.
