Not sure if it's in an overlay, but I don't think it's in portage. Run eix -l backup and see how many back up tools and scripts pop up. I have been using tar, star and rsync. They all work and they can all make incremental back ups. You'll find that a lot of the other 'smart' back up applications are based on these anyway. HTH. -- Regards, Mick
