Data Deduplication and Disk-to-Disk Backup Systems: Technical Considerations

What you need to know—and ask—before implementing a
data deduplication solution

Presenter: Heidi Biggar, Analyst, Enterprise Strategy Group

This on-demand podcast explores the primary technological differences inherent in the various forms of data deduplication currently available:

Deduplication ratios vary by application and methodology
How data deduplication effects backup and restore performance
The benefits of one type of deduplication technology over another
(e.g., inline vs. post-process)
The level of support for remote replication
The impact on disaster recovery windows
Ease of implementation

As an analyst for ESG, Heidi Biggar focuses on D2D backup solutions, including VTL, D2D appliances, and CDP solutions. Heidi is a veteran of the storage industry and former senior technical editor at InfoStor magazine.

"Data de-duplication is a powerful form of virtualization—the ability to logically view and manage physical assets for greater utilization and automation of otherwise manual tasks. Data de-duplication achieves both of these goals by significantly reducing the amount of capacity required to store backup data—5:1, 10:1, 20:1 and beyond. Additionally, data de-duplication reduces or even eliminates the need to manage tapes. Dealing with tape media management is archaic in this digital age. It is analogous to someone still stubbornly hand washing the dishes even though he or she has dishwasher right next to the sink."
