Was looking for comparisons and this is the best one I found: https://gist.github.com/alexbarton/6c84f74bc6a4be1b8664c26af...

Edit: Also, looks like this isn't easy to get going on Alma Linux, Rocky Linux, and most likely Redhat. Couldn't find any binaries or installation instructions other than the bup build from source instructions which were quite lengthy and I did not give them a shot. It requires a lot of other libs to be installed, python modules etc, and I'm not looking to add a bunch of stuff to test a backup util :(
