Joe's Guide to Mac Backup Software: This appendix is now hugely expanded, and it compares nearly 100 different backup applications. It was moved online to make it easier to update.

Retrospect Primer: This appendix provides procedures for setting up duplicates and archives in Retrospect Desktop and Retrospect Express, along with a brief look at Retrospect's terminology, logic, and interface. It was moved online to keep the size of this book more manageable; now that so many more options exist for making backups, it seemed somewhat out-of-scope to devote over 20 pages to the aging Retrospect.
