If you rsync a directory, all previous changes are lost. If you rsync to a different directory every time to keep different versions, you might as well use tar, because rsync won't save a lot of space/time in that case. And dump will backup all ufs2 features such as flags and acls. I'm not sure if rsync can manage that. It's also easy to compress dumps, which can save a lot of space. But if you need to lift a single file from a backup, it might be easier with rsync, although dump has an interactive mode to select stuff to restore as well. A compelling reason to use rsync would be if the file system that is to be backed up is so large that more than one backup won't fit on your backup disk anyway. In that case rsync can save you a lot of time.
