Using rsync for backups, because it's not shiny and new (tinkerbetter.tube)

You might not even like rsync. Yeah it's old. Yeah it's slow. But if you're working with Linux you're going to need to know it.

In this video I walk through my favorite everyday flags for rsync.

Here's a companion blog post, where I cover a bit more detail: https://vkc.sh/everyday-rsync

Also, @BreadOnPenguins made an awesome rsync video and you should check it out: https://www.youtube.com/watch?v=eifQI5uD6VQ

Lastly, I left out all of the ssh setup stuff because I made a video about that and the blog post goes into a smidge more detail. If you want to see a video covering the basics of using SSH, I made one a few years ago and it's still pretty good: https://www.youtube.com/watch?v=3FKsdbjzBcc

The thing I hate most about rsync is that I always fumble to get the right syntax and flags.

This is a problem because once it’s working I never have to touch it ever again because it just works and keeping working. There’s not enough time to memorize the usage.

One trick that one of my students taught me a decade or so ago is to actually make an alias to list the useful flags.

Yes, a lot of us think we are smart and set up aliases/functions and have a huge list of them that we never remember or, even worse, ONLY remember. What I noticed her doing was having something like goodman-rsync that would just echo out a list of the most useful flags and what they actually do.

So nine times out of 10 I just want rsync -azvh --progress ${SRC} ${DEST} but when I am doing something funky and am thinking "I vaguely recall how to do this"? dumbman rsync and I get a quick cheat sheet of what flags I have found REALLY useful in the past or even just explaining what azvh actually does without grepping past all the crap I don't care about in the man page. And I just keep that in the repo of dotfiles I copy to machines I work on regularly.

Most Unix commands will show a short list of the most-helpful flags if you use --help or -h.
