Unix Backup & Recovery provides a complete overview of all facets of Unix backup and recovery, and offers practical, affordable backup and recovery solutions for environments of all sizes and budgets. The book begins with detailed explanations of the native backup utilities available to the Unix administrator, and ends with practical advice on choosing a commercial backup utility.
This book: Describes the features, limitations, and syntax of Unix backup and restore utilities,(including dump, tar, cpio, dd, GNUtar, and GNUcpio) for many popular versions of Unix, including AIX, Compaq Unix, HP-UX, IRIX, SCO, Solaris, and Linux Provides instructions for installing and configuring freely available backup systems such as AMANDA Includes ready-to-run shell scripts that automate live backups of Informix, Oracle, and Sybase databases Presents step-by-step recovery procedures for Oracle, Informix, and Sybase Presents step-by-step "bare-metal" disaster recovery procedures for AIX, Compaq Unix, HP-UX, IRIX, Solaris, and Linux Describes the design of "disaster recovery" and "highly available" systems Provides guidance on choosing a commercial backup and recovery system Describes the features and limitations of backup hardware
Rezensionen / Stimmen
"In conclusion, this is a reference, that is so profoundly useful that you should start to use it routinely to underpin knowledge in yur day-to-day work. Before I read this book I only considered three manuals as key personal references to be kept close to hand at all times (all of them "O'Reillys"). They were: Practical UNIX and Internet Security by Garfinkel, Spafford and Schwartz, TCP/IP Network Administration by Hunt and Essential System Administration by Frisch I now have a fourth to add to this list. Wherever I go, whatever systems I end up administering, these four books will be nearby. I urge you to do the same." - Steven-Ashley Woltering, Ping (HP User Group Technical Journal), May

W. Curtis Preston has specialized in designing backup and recovery systems for over six 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 a principal consultant for Collective Technologies, where they have developed a proven system for choosing a commercial backup utility when the environment and budget allow one to be purchased. This system has been used to select commercial backup systems for some of the world's largest environments, including a six terabyte Oracle database and one site with a total storage capacity of five petabytes. Once software and hardware selection is completed, they design and implement a complete system based on the customer's requirements. Curtis states that he could have never written the book without the use of the Collective Intellect(TM), or the "C.I." as he calls it. Collective Technologies' 400 consultants have administered every major operating system, and they support each other by freely sharing their "collective" experiences, referred to as the Collective Intellect(tm). While writing the book, Curtis asked the C.I. hundreds of questions that would have taken him years to research on his own. In a few cases, entire chapters were written by people who demonstrated expertise in a certain area. Curtis believes that the C.I. has made this a far better book than he ever envisioned.
