Abstract

Disk-based deduplication storage has emerged as the new-generation storage system for enterprise data protection to replace tape libraries. Deduplication removes redundant data segments to compress data into a highly compact form and makes it economical to store backups on disk instead of tape.

The primary challenge of building a deduplication sytem is limited amount of memory to index all of the data in a multi-terabyte system. Done naively performance will be limited by the random access performance of the underlying hard drives. This talk will discuss Data Domain's approach to avoiding the disk bottleneck, deduplication's relationship to traditional compression and some future technology directions.
