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

slow

rsync is pretty fast, frankly. Once it's run once, if you have -a or -t passed, it'll synchronize mtimes. If the modification time and filesize matches, by default, rsync won't look at a file further, so subsequent runs will be pretty fast. You can't really beat that for speed unless you have some sort of monitoring system in place (like, filesystem-level support for identifying modifications).

yeah, more often than not I notice the bottleneck being the storage drive itself, not rsync.

Can also use fpsync to speed things up. Handles a lot for you
