WHITE PAPER & ON-DEMAND WEBCAST
Data Deduplication and Disk-to-Disk Backup Systems: Technical Considerations
What you need to know—and ask—before implementing a
data deduplication solution
Author and Presenter: Heidi Biggar, Analyst, Enterprise Strategy Group
This vendor-neutral report and webcast examines the technological considerations of implementing deduplication, including a list of the key questions ESG believes every organization should ask before making any purchasing decisions.
This paper helps to clarify some of the confusion that exists around data deduplication:
- What deduplication ratio you can realistically expect to see
- The effect of data deduplication on 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. She is well-known in end-user, vendor and analyst circles for her thorough and insightful coverage of existing and emerging storage technologies, markets and trends.
"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."
