Bob LeVitus has written an e-book that contains everything one needs to know about data backup on a Macintosh. "Dr. Mac" described, in a story at The Chronicle Tuesday how it all got started and whatis contained in his book "Dr. Macis Guide to Backing Up Your Mac."
The on-line version is free to view right here at The Mac Observer. There is a link on the first page on how to purchase the PDF file for just US$3.99.
Dr. LeVitus also wrote about an additional resource: "For even more detailed information on backing up your Mac, the nice folks at Take Control e-books recently released Take Control of Mac OS X Backups, a 176-page e-book by Joe Kissell. It includes backing up when you travel, SANs (Storage Area Networks) and NAS (Network Attached Storage) devices, command-line backup systems, and much more. A free 33-page PDF sample is available."
A frequent contributor to The Mac Observer, Bob "Dr. Mac" LeVitus writes a column called Dr. Mac: Rants and Raves.
