Summary: Great backup, lousy restore
I just tested this software. It does a great job backing up, with lots of options. Backups can be native file format in a Finder folder hierarchy, so you can search them with any search utility. Iterative backups get made within the same folder hierarchy, in dated folders. It's fast. It's smart.
Unfortunately, Tri-BACKUP's restore functionality is, AFAICT, extremely limited. You can't simply tell it to restore a folder to how it was at last backup ... or at a given date in the past ... or how it was when some previous backup got made. Nope, you've got to manually page through a file list to decide which version of what gets restored. Since I have over 250,000 files in my Documents folder alone, plus a huge photo archive, restoring using Tri-BACKUP just isn't practical.
Too bad, because otherwise it's a nice program, and I've heard very good reports about its reliability.
