I've just finished a significant update of my online appendix to "Take Control of Mac OS X Backups" that lists just about every graphical Mac backup program in existence. Although I had tweaked the tables here and there over the past few months, I had also been maintaining a separate list of new and updated backup programs that required more testing before I could properly list them. When that list grew to more than 20 items, I realized I'd better take action before it collapsed under its own weight.
In addition to updated details on numerous backup programs, the list now includes several entirely new entries, including ElephantDesktop, IBackup for Mac, IDrive Online Backup, and Mathusalem. In addition, I've promoted SugarSync to the "real backup software" portion of the tables now that it includes versioning (as discussed in "SugarSync Sweetens Online Syncing," 2008-08-30).
I'm also aware of a couple of programs in beta testing, and as soon as I get my hands on shipping versions, I'll include those as well. Meanwhile, as I was typing this post, I saw yet another update appear for one of the backup programs in my table (and yes, I've already updated it). Jeesh!
