Carbonite issues
I'm a Carbonite user at the moment, planning to switch to (most likely) CrashPlan. Carbonite has a number of problems which CrashPlan et al don't suffer from: in particular limited retention of file versions (inc removal of backups of deleted files), lack of support for backing up external drives, throttled upload speeds, failure to detect file/folder moves.
Finally a major Carbonite bug I ran into that they indicate they have no intention of fixing: some software apps like Dreamweaver use a file save method that causes Carbonite to think the file has been deleted and immediately recreated. This causes all version history to be lost each time the file is saved!
