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 works fine if all you need is transfer, my issue with it it’s just not efficient. If you want a “time travel” feature, your only option is to duplicate data. Differential backups, compression, and encryption for off-site ones is where other tools shine.
I have it add a backup suffix based on the date. It moves changed and deleted files to another directory adding the date to the filename.
It can also do hard-link copied so that you can have multiple full directory trees to avoid all that duplication.
No file deltas or compression, but it does mean that you can access the backups directly.
Agree. It’s neat for file transfers and simple one-shot backups, but if you’re looking for a proper backup solution then other tools/services have advanced virtually every aspect of backups so much it pretty much always makes sense to use one of those instead.
