“With the DD460 from Data Domain,
we’ve been able to compress and store two to three months of backup data
onsite. We’ve cut costs and reduced our reliance on offsite tape storage,
and we can back up and restore data at incredible speeds. Best of all, we can
easily verify the security and integrity of our data. We’re very pleased
— the DD460 is everything we’d hoped for.”

Systems and storage expert Barb Goldworm describes the benefits of deduplication and D2D backup for DR and how these techniques are extended to deliver cost-effective offsite data protection. Two case studies are presented to illustrate in detail the cost savings and return on investment. You will learn: the benefits of deduplication and D2D backup; how D2D can be extended to deliver cost-effective offsite data protection and DR; and how to build a business case for WAN vaulting.

Barb Goldworm from Focus Consulting interviewed three enterprise customers who have adopted a disk-based backup solution within their data center. With the kind of ROI achieved by these customers (up to-523%), along with the Total Savings (up to $1.4m), and the types of payback periods experienced (4-5 months), it is clear that Data Domain offers proven cost savings and a strong, persuasive business case across a variety of scenarios.

This paper by GlassHouse Technologies provides an in-depth analysis of how Data Domain deduplication storage offers new storage architecture options for EMC NetWorker customers. The authors conclude: "We see a particularly compelling case for Data Domain to revolutionize the way small, medium, large and remote NetWorker sites manage physical storage resources and replication for disaster recovery."

The Bakbone NetVault: Backup Virtual Tape Library (NVBU VTL) is a built-in tape emulation feature that gives disk storage the look and feel of a tape library with the added benefits of greater speed, reduced costs and sophisticated media manage¬ment capabilities. Data Domain storage systems can serve as a NAS appliance hosting an NVBU VTL or as a Fibre Channel VTL within a NetVault: Backup environment, providing customers with reduced backup windows and a powerful and cost-effective disk-to-disk-to-tape (D2D2T) solution. This paper outlines the joint solution.

This paper demonstrates how Data Domain systems provide a 10-30x compression to CommVault Galaxy backup data. This enables customers to retain months of backup images for less than $.35/GB, a price that is comparable to tape. Data Domain systems also enable network-efficient WAN vaulting for disaster recovery, remote office data protection and tape consolidation – all under the control of CommVault Galaxy.

This white paper, written by John Merryman from GlassHouse Technologies, focuses on how Data Domain storage solutions integrate with standard TSM architectural and operational environments. Data Domain provides an alternative storage solution for TSM customers faced with never-ending data growth and data protection challenges, by eliminating unnecessary TSM data storage via data deduplication and compression. Data deduplication is performed inline on incoming data streams, recognizing redundant segments and storing them as unique instances within the Data Domain Restorer file system.

Oracle Recovery Manager (RMAN) is a built-in tool that allows the Database Administrator (DBA) to easily backup and recover the data in an Oracle database. RMAN handles the coordination required to ensure that transaction integrity is preserved and sufficient information is maintained to recover the database to any appropriate point. This technical best practices and implementation guide will describe how a Data Domain appliance is typically used as a target for backup or archived data. Learn about the characteristics that make Data Domain deduplication storage systems ideal for RMAN backup.

Proliferation and preservation of many versions and copies of data drives much of the tremendous data growth most companies are experiencing. IT administrators are left to deal with the consequences. Because deduplication addresses one of the key elements of data growth, it should be at the heart of any data management strategy. This paper demonstrates how storage systems can be built with a deduplication engine powerful enough to become a platform that general applications can leverage.

Will traditional data protection applications survive the demands for ultra-high availability and the growing requirements for nearly instantaneous recovery? In this paper, data protection expert Fred Moore of Horison Information Strategies explores today’s backup and recovery strategy options, comparing traditional methods, such as Backup, Disk Mirroring, Snapshots, CDP, and VTLs. What are the trade-offs associated with each and, more important, how do new data deduplication techniques change storage economics and impact data protection decisions and purchases?

Disaster recovery and remote office replication are top-of-mind issues for IT professionals as natural disasters and human errors continue to underscore the fallibility of the tape-based backup strategies. Data Domain disk-based systems dramatically improve the speed and efficiency with which disaster recovery can occur — and eliminate tapes and trucks once and for all.

A significant challenge with deduplication technology is to identify and eliminate duplicate data segments on a low-cost system that cannot afford enough RAM to store an index of the stored segments and may be forced to access an on-disk index for every input segment. This highly technical paper describes three techniques employed in the production Data Domain deduplication file system to relieve the disk bottleneck.

Data Domain has proven that deduplication can be reliable, fast and easy to manage, all while providing massively disruptive economic differentiation for backup deployments seeking greater retention, replication and recovery speed. A consensus is now emerging that for many other non-backup nearline applications, deduplication will bring the same dramatic impact. Read how deduplication can optimize storage for application protection utilities (such as Oracle RMAN), operating system images, online reference data and archiving.

Data Domain protection storage systems represent a dramatic departure from conventional storage system design thinking and introduce a radical premise: No single mechanism is sufficient to ensure data integrity in a storage system. Data Domain systems have been designed from the ground up to be the storage of last resort, and include Data Domain’s Data Invulnerability Architecture, the industry’s best defense against data integrity issues.

Tape has been losing ground to deduplication in disk systems, which over time can deliver an order of magnitude greater data reduction than traditional compression. In SISL (Stream Informed Segment Layout), Data Domain has developed a proven architecture that uses deduplication to achieve high throughput with economical storage hardware. Over time, this will allow the continued scaling of CPUs to add direct benefit to system scalability in the form of additional throughput.
