      We tell people to make backups. Occasionally we might mention the
      difference between full, differential, and incremental backups. If we
      are turning out hotshot forensics specialists we might even go into
      the difference between file image backups and disk image backups. But
      how often do we tell people that operational databases (which is most
      of them) have open files, and generally prevent you from backing up
      with the usual utilities?

      Part one is an introduction. Chapter one is an overview of some quick
      aspects about backups, but primarily is a suggestion to do it, and do
      it properly. Basic types of backups, and the factors affecting backup
      procedures, are outlined in chapter two. (The material will probably
      feel very familiar to those who have worked in the business continuity
      field: not just because of the importance of backups in recovery
      operations, but also because of the analysis of the complex and
      interdependent linkages that can cause disasters.)

      Part two examines open source backup utilities. (Most of them are
      open source: a few are just "free.") Chapter three reviews some of
      the utilities for UNIX, Linux, Windows, and the Mac that can provide
      fundamental backup capabilities, and which can also be used by other
      applications for more sophisticated backup systems. Amanda (the
      Advanced Maryland Automated Network Disk Archiver), an open source,
      cross-platform, client/server architecture (Windows servers do not
      appear to be available, but clients are) backup system that uses some
      of these underlying tools is described in chapter four. Amanda has
      some very interesting security and scheduling provisions. BackupPC, a
      network-based backup system for UNIX (client or server) and Windows
      (client) is briefly described in chapter five. Chapter six explains
      another distributed system, Bacula, in a rather haphazard manner.
      Rsnapshot, which does near-continuous backup, is delineated in chapter

      Part three supposedly turns to commercial backup products. In fact,
      the contents are simply a list of factors to be used when evaluating
      software products (chapter eight) and various types of hardware

      Bare-metal recovery (what you do to restore the system when you've
      lost the whole thing, rather than just a few files) is described in
      part four. The Solaris flash archive is intended for cloning of
      systems, but chapter ten tells how to use it for recovery. Chapter
      eleven explains tools and procedures for Linux, and a little tiny bit
      for Windows as well. Procedures for HP-UX are in twelve, AIX in
      thirteen, and Mac OS X (which basically has a version of BSD under the
      graphical user interface) is in fourteen.

      Database systems have a) lots and lots of data, b) special backup
      requirements, and c) a special importance to most companies, so this
      application gets special attention in part five. General concepts are
      discussed in chapter fifteen, with the particulars of backup and
      recovery for Oracle, Sybase, DB2, SQL Server, Microsoft's Exchange
      (well, an email server certainly *uses* a database ...), PostgreSQL,
      and MySQL in chapters sixteen to twenty-two.

      Part six covers miscellaneous topics. Actually, it is chapter twenty-
      three that contains miscellaneous topics (starting out with how to
      back up VMWare servers). Chapter twenty-four is a justification for
      the book (or, for having a backup process, anyhow).

      Preston's work is directed at inexpensive backup solutions for open
      systems, so it is not surprising that UNIX utilities get the most
      space and the greatest attention to detail. Windows is certainly not
      ignored, and the author even bends his own rules to accommodate some
      helpful utilities in the Windows realm, but there simply isn't a lot
      of material to work with.

      Backups are important for everyone. This book is not for everyone.
      The text will be very valuable for those who have large systems, or
      large numbers of systems, with backup needs complicated by special

      Now go make a backup.
