“In this article, I will investigate commonly used GUI backup/cloning tools for Mac OS X. The tools vary widely with respect to their feature set; the features are irrelevant here. I will concentrate purely on the underlying functionality of copying files. A backup tool needs to be able to copy files faithfully for a successful restore in case desaster has struck. The surprising conclusion of my investigation is that almost all Macintosh Backup tools fail at their most basic task, the faithful copying of files.”
