Packed with practical, freely-available backup and recovery solutions for Unix, Linux, Windows and Mac OS X systems - as well as various databases - this new guide is a complete overhaul of Unix Backup & Recovery by the same author, now revised and expanded with over 75 per cent new material. "Backup & Recovery" starts with a complete overview of backup philosophy and design, including the basic backup utilities of tar, dump, cpio, ntbackup, ditto, and rsync. It then explains several open source backup products that automate backups using those utilities, including AMANDA, Bacula, BackupPC, rdiff-backup, and rsnapshot. "Backup & Recovery" then explains how to perform bare metal recovery of AIX, HP-UX, Linux, Mac OS, Solaris, VMWare, & Windows systems using freely-available utilities. The book also provides overviews of the current state of the commercial backup software and hardware market, including overviews of CDP, Data De-duplication, D2D2T, and VTL technology. Finally, it covers how to automate the backups of DB2, Exchange, MySQL, Oracle, PostgreSQL, SQL-Server, and Sybase databases - without purchasing a commercial backup product to do so.For environments of all sizes and budgets, this unique book shows you how to ensure data protection without resorting to expensive commercial solutions. You will soon learn to: automate the backup of popular databases without a commercial utility; perform bare metal recovery of any popular open systems platform, including your PC or laptop; utilize valuable but often unknown open source backup products; understand the state of commercial backup software, including explanations of CDP and data de-duplication software; and access the current state of backup hardware, including Virtual Tape Libraries (VTLs).show more

About W.Curtis Preston

W. Curtis Preston has specialized in designing backup and recovery systems for over eight years, and has designed such systems for many environments, both large and small. The first environment that Curtis was responsible for went from 7 small servers to 250 large servers in just over two years, running Oracle, Informix, and Sybase databases and five versions of Unix. He started managing this environment with homegrown utilities and eventually installed the first of many commercial backup utilities. His passion for backup and recovery began with managing the data growth of this 24x7, mission-critical environment. Having designed backup systems for environments with small budgets, Curtis has developed a number of freely available tools, including ones that perform live backups of Oracle, Informix, and Sybase. He has ported these tools to a number of environments, including Linux, and they are running at companies around the world. Curtis is now the owner of Storage Designs, a consulting company dedicated entirely to selecting, designing, implementing, and auditing storage systems. He is also the webmaster of more
