It discusses the impact of backup and data replication, the often misapplied B2D and D2D strategies, and “tapeless" backup environments. Continuous data protection and remote replication strategies are also addressed as they are integrated within backup strategies - a very important topic today. \* Learn backup solution design regardless of specific backup software \* Design realistic recovery solutions \* Take into account new data protection standards and the impact of data replication Whether you are using NetBackup, CommVault, or some other backup software, Pro Data Backup and Recovery will give you the information you need to keep your data safe and available. What you'll learn \* Elements of a backup environment and applications of those elements \* New technologies within the backup technology area and their impact on design \* Configurations using both Symantec NetBackup and CommVault Simpana, with combinations of backup serves, media servers, and clients, and the impacts of each combination \* Combinations of both hardware and software configurations that are scalable from small to large environments \* Designs that address perennial problem areas such as remote offices, very short (less-than-15-minute) recovery point objectives (RPOs), and tape management \* Reporting requirements that will assist in maintaining and growing an implementation once executed Who this book is for The general audience for this book includes systems engineers, systems administrators, and specialist backup administrators. Table of Contents \* Introduction to Backup and Recovery \* Backup Software \* Physical Backup Media \* Virtual Backup Media \* New Media Technologies \* Software Architectures: CommVault \* Software Architectures: NetBackup \* Application Backup Strategies \* Putting It All Together: Sample Backup Environments \* Monitoring and Reporting \* Summary Steven has been a Sys Admin/Engineer for over 15 years, covering operating systems from SVR3.2, Microsoft Windows, RedHat Linux, HP-UX and, of course, the many versions of Solaris. He has a background with scripting in KSH, SH, and Perl, as well as application development in C and VB. Â He was the Lead Backup and Recovery Engineer for Washington Mutual Bank, and am currently the Western region's Regional Technical Consultant for EMC's Backup, Recovery and Archiving (BURA) practice, supporting 5 other Local Technical Consultants, and covering over 100 Enterprise level accounts. I have been published in SysAdmin Magazine (Aug 1999), discussing aspects of Fibre Channel and its implementation within the environment in which I worked at the time. I currently hold a Brocade CFP, EMC Backup and Recovery Specialist certifications, as well as various UNIX Operating system certifications. Good backup and recovery strategies are key to the health of any organization. Medium- to very-large-scale systems administrators have to protect large amounts of critical data as well as design backup solutions that are scalable and optimized to meet changing conditions. Pro Data Backup and Recovery will cover some of the more common backup applications, such as Symantec NetBackup/BackupExec, EMC NetWorker, and CommVault, but the main discussion will focus on the implementation of 21st century architectures that allow the backup software to be a "commodity" item. The underlying architecture provides the framework for meeting the requirements of data protection for the organization. This book covers new developments in data protection as well as the impact of single-instance storage upon backup infrastructures. It discusses the impact of backup and data replication, the often misapplied B2D and D2D strategies, and "tapeless" backup environments. Continuous data protection and remote replication strategies are also addressed as they are integrated within backup strategies—a very important topic today.
