“Since implementing the Data Domain Restorer we have
retired the six DLT tape drives and the 126 tapes used to back-up our data stores.
We now rely on the Restorer for all our back up and restore needs.”

The benefits of virtualized environments often come at the cost of extra storage, backup resources and administrative challenges. Data Domain deduplication storage offers a way out by reducing redundant data across VMware data backups, operating at disk speeds, and providing cost-effective replication for fast DR using backup images. This guide outlines best practices for architecting a backup/recovery/DR approach for VMware using Data Domain storage, regardless of which backup software or scripts are involved.

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.

Oracle Recovery Manager (RMAN) allows the Database Administrator (DBA) to easily backup and recover 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 best practices and implementation guide describes how a Data Domain appliance is typically used as a target for backup or archived data.

Enterprises today are faced with a two-sided challenge: to store and manage increasing amounts of data and to simultaneously reduce system footprint — and in a way that enables enterprises to meet recovery requirements. Deduplication is a technique that can dramatically improve storage system performance, minimize capacity requirements, and speed up data recovery. This workbook helps you assess current needs and usage and determine where deduplication can positively affect your IT consolidation initiatives, help reduce costs, and create a more "green" environment.

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?

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 Retention Lock software also makes these nearline systems useful for IT organizations challenged with compliance to corporate governance policies.

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.
