I think a good followup question for this one would be “Were you able to answer the question from memory?”

I couldn’t remember, so I had to do some typing to see. And based on the amount of visible keycap wear, I’d say they get used equally.

You’re going to have to answer to the blue man group.

My one and only purpose was to warn them that their “drawback” is more of a gator pit. It’s noble that you’re here defending rsync’s honor, but maybe let them know instead? My preferred backup tool has “don’t eat my data” mode on by default.

Sure, but that’s not in their answer.

only drawback is that it doesn’t create differential backups

This is a big drawback because even if you don’t need to keep old versions of files, you could be replicating silent disk corruption to your backup.
