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

    Maybe I am missing something but how does it handle snapshots?

    I use rsync all the time but only for moving data around effectively. But not for backups as it doesn’t (AFAIK) hanld snapshots

      You get incremental backups (snapshots) by using

      --link-dest=DIR         hardlink to files in DIR when unchanged

      To use this you pass in the previous snapshot location as DIR and use a new destination directory for the current snapshot. This creates hard links in the new snapshot to the files which were unchanged from the previous snapshot, so only the new files are transferred, and there is no duplication of data on disk (for whole-file matches).

      This does of course require that all of the snapshots exist in the same filesystem, since you cannot hard-link across filesystems.

        Ah, I didn’t know of this. This should be in the linked article! Because it’s one of the ways to turn rsync into a real backup! (I didn’t know this flag- I thought this was the main point of rdiff-backup.)

      yeah, it doesn’t, it’s just for file transfer. It’s only useful if transferring files somewhere else counts as a backup for you.

      To me, the file transfer is just a small component of a backup tool.
