资源说明：This book is divided into six parts:
Part I, Introduction
This part of this book contains just enough information to whet your backup and recovery
appetite.
Chapter 1, Preparing for the Worst, contains the six steps that you must go through to create
and maintain a disaster recovery plan, one part of which will be a good backup and recovery
system.
Chapter 2, Backing It All Up, goes into detail about the essential elements of a good backup
and recovery system.
Part II, Freely Available Filesystem Backup & Recovery Utilities
This section covers the freely available utilities that you can use to back up your systems if you
can't afford a commercial backup package.
Chapter 3, Native Backup & Recovery Utilities, covers Unix's native backup and recovery
utilities in detail, including dump, tar, GNU tar, cpio, GNU cpio, and dd.
Chapter 4, Free Backup Utilities, starts with some simple tools to assist you in your backups,
and contains a complete overview of the popular AMANDA utility, which is used to back up
many small to medium-sized Unix installations around the world.
Part III, Commercial Filesystem Backup & Recovery Utilities
If you have outgrown the capabilities of free utilities, or would just like to take advantage of
new backup and recovery technologies, you'll need to look at a commercial product.
Chapter 5, Commercial Backup Utilities, is your guide to the hundreds of features available in
the over 50 commercial backup products available on the market today, allowing you to make
an educated purchase decision.

Chapter 6, High Availability, details how, when backups just aren't fast enough, a high
availability system is designed to keep you from ever needing to use your backups.
Part IV, Bare-Metal Backup & Recovery Methods
A bare-metal recovery is the fastest way to bring a dead system back to life, even if its root
drive is completely destroyed.
Chapter 7, SunOS/Solaris, contains an in-depth description of the "homegrown" bare-metal
recovery procedure that can also be used to back up Linux, Compaq, HP-UX, and IRIX, as
well as a detailed Solaris-based example of bare-metal recovery.
Chapter 8, Linux, detail how you can perform a bare-metal recovery of a Linux system with a
floppy, a backup device, pax, and lilo.
Chapter 9, Compaq True-64 Unix, covers both Compaq True-64 Unix's bare-metal recovery
tool and the Compaq version of the homegrown procedure covered in Chapter 7.
Chapter 10, HP-UX, covers the make_recovery tool, which now comes with HP-UX to
perform bare-metal recoveries, along with the HP version of the homegrown procedure.
Chapter 11, IRIX, explains how the different versions of IRIX's Backup and Restore scripts
work, as well as the IRIX version of the homegrown procedure.
Chapter 12, AIX, discusses AIX, a procedure that does not support the homegrown procedure
discussed in Chapter 7, but does use mksysb, probably one of the oldest and best-known
bare-metal recovery tools.
Part V, Database Backup & Recovery
This section explains in plain language an area that presents some of the greatest backup and
recovery challenges that a system administrator or database administrator will face-backing up
and recovering databases.
Chapter 13, Backing Up Databases, is a chapter that will be your friend if you're an SA who's
afraid of databases or a DBA learning a new database. It explains database architecture in
plain language, while relating each architectural element to the appropriate term in Informix,
Oracle, and Sybase.
Chapter 14, Informix Backup & Recovery, explains both the older ontape and the newer
onbar, after which it provides a logically flowcharted recovery procedure that can be used
with either utility.
Page xviii
Chapter 15, Oracle Backup & Recovery, explains how to perform Oracle hot backups whether
you are using Oracle's native utilities, EBU, or RMAN, and then provides a detailed flowchart
guiding you through even a difficult recovery.
Chapter 16, Sybase Backup & Recovery, shows exactly how to use the Backup Server utility,
including another flow chart to guide you through Sybase recoveries.
Part VI, Backup & Recovery Potpourri
The information contained in this part of the book is by no means unimportant; it simply
wouldn't fit anywhere else!
Chapter 17, ClearCase Backup & Recovery, explains in detail the unique backup and recovery
challenges presented by ClearCase.
Chapter 18, Backup Hardware, explains the many different types of backup hardware
available today, as well as providing criteria that you may use to decide which type of backup
drive is right for you.
Chapter 19, Miscellanea, covers everything from the oft-debated "live filesystem dumps"
question to a few jokes that I found about backup and recovery!
