Deduplication White Papers

Toss the Tape: 7 Key Steps for Overcoming the Limitations of Tape Backup

Abstract: This document is a 7-step guide for making the move from tape to disk backup with deduplication. Within these steps, the Guide provides a concise summary of the downsides of tape backup, and then examines the superiority and economy of second-generation disk backup with data deduplication. It also presents key functional requirements for a disk backup system with deduplication as well as a framework for assessing the cost savings of a disk-based backup system with data deduplication vs. tape.

Optimizing Backup and Data Protection in Virtualized Environments

Abstract: The promise of maximizing IT investments while minimizing complexity has resulted in widespread adoption of server virtualization. In fact, VMware users are now deploying nearly half of their new servers as virtual servers, rather than as physical servers. That said, rapid adoption of server virtualization has brought with it a variety of challenges in backup and data protection. This white paper examines the return on investment of server virtualization and its impact on backups and overall data protection.

Achieving Cost Savings in Backup with Deduplication

Abstract: The environment for all businesses has changed dramatically in the past year. This means significantly increased scrutiny of IT budgets that were already being closely watched. New projects will have to pass the test of clear need and the question will be asked "can you do without." While many IT projects will be reduced along with budgets, one truism remains: the amount of data an organization creates and must retain continues to grow. This whitepaper discusses this paradox and offers a way to eliminate it with real-world examples of cost savings and results related to disk backup with deduplication.

The Benefits of Second Generation Disk-based Backup Technology

Abstract: As disk prices are falling, backup to disk has become a reality. However, many organizations quickly find that without compression and data deduplication that the amount of disk required to maintain backup retention is cost prohibitive.

Over the past couple years, first generation disk-based backup systems with data deduplication technology have alleviated some of the challenges associated with backing up to disk, but these systems have their challenges as well. Newer, second-generation systems improve upon disk-based backup with deduplication and eliminate the challenges of the 1st generation systems.

Data Deduplication Methodologies

Comparing ExaGrid's Byte-Level Data Deduplication to Block Level Data Deduplication

Marc Crespi | VP, Product Management, ExaGrid Systems

Abstract: Though data deduplication technologies have been around for years, there is a renewed focus on them recently as they are being utilized by products in the disk-based backup market. Data deduplication enables disk to be a feasible long-term retention backup media -- making it the same or lower cost than tape-based systems.

Five Key Considerations for Evaluating the Scalability of Disk-based Backup Solutions

Marc Crespi | VP, Product Management, ExaGrid Systems

Abstract: In selecting a disk-based backup solution, it's critical to consider the scalability of each prospective solution to ensure that it will meet the needs of your organization now and into the future. This paper outlines the five key questions you should ask when evaluating the scalability of any disk-based backup solution.
