I use obnam, and I've just read the manuals for bup and borg. It seems like obnam is more featureful and has better porcelain than either bup or borg, so that the script you end up writing to automate your backups is much simpler. But it is fairly slow. There are some tuning flags that will make it much faster than the default, but I would not at all be surprised if bup and borg are both much faster.
