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

rsnapshot is a script for the purpose of repeatedly creating deduplicated copies (hardlinks) for one or more directories. You can chose how many hourly, daily, weekly,... copies you'd like to keep and it removes outdated copies automatically. It wraps rsync and ssh (public key auth) which need to be configured before.

Hardlinks need to be on the same filesystem, don't they? I don't see how that would work with a remote backup...?

The hard links aren’t between the source and backup, they’re between Friday’s backup and Saturday’s backup

Ahh, ok. Thanks for clarifying.
