I really make backups only a few times. I have the configuration files of my systems on my GitHub and Codeberg. The rest, I don't need; the only things I keep are books and music that I download from the internet, which I have on a 1TB external hard drive.

When I have made a backup for a specific reason, I have done it with rsync. It's a tool that works quite well and is for the command line.

This.

I tried it some time ago and I had to format the SSD because the operating system became unusable.

Yes, I actually stopped following RSS/Atom feeds. If I want to look something up, I do it from the web browser.

I used it for a while. It's pretty good.
