I use CrashPlan. It's worked pretty well as far as I can tell. I haven't actually tested restoring from it. The UI is super-slick, at least, and it works well on all three major platforms.
CrashPlan has a selector in the settings for what percent of CPU and I/O bandwidth it's allowed to use. Personally I bumped it up to 100 because I never noticed any performance degradation (and it backs up faster this way.) If I want to see something abusing my CPU way more than 25% I just have to load a web browser anyway.
