Can you please share your backup strategies for linux? I'm curious to know what tools you use and why?How do you automate/schedule backups? Which files/folders you back up? What is your prefered hardware/cloud storage and how do you manage storage space?
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.
