yup, it seemed the best of the three or four I tried, and very configurable to boot, especially for a free version. I have it set up to back up from my windows to my linux box when the two are both on, an incremental backup that lets me delete less necessary stuff on my pc (e.g. all the "less good" photos I've taken), safe in the knowledge that I do still have a copy over there.
(I also do a regular backup of what's on the linux box to DVD for completeness once every couple of months or so)
