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

It's single thread, one file at a time.

That would only matter if it's lots of small files, right? And after the initial sync, you'd have very few files, no?

Rsync is designed for incremental syncs, which is exactly what you want in a backup solution. If your multithreaded alternative doesn't do a diff, rsync will win on larger data sets that don't have rapid changes.

For a home setup that seems fine. But I can understand why you wouldn't want this for a whole enterprise.
