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

For versioning/retention, just use snapshots in whatever filesystem you're using (you are using a proper filesystem like ZFS or BTRFS, right?).

How does that get sent over rsync though? Wouldn't you need snapshots on the remote destination server?

Why not just use a backup utility instead?

Yes, async copies files to the remote server, the remote server takes regular snapshots.

Why not just use a backup utility instead?

What is that utility providing that snapshots + rsync doesn't. If rsync + snapshots is sufficient, why overcomplicate it with a backup utility?

[–] MangoPenguin@lemmy.blahaj.zone 1 points 2 hours ago

The main things that come to mind are you have to test/monitor 2 seperate actions instead of 1, and restores of single files could be more difficult since you need to login to the backup server, restore the file from a snapshot, then also copy that file back to your PC.
