Mastering the rsync file synchronization tool can be immensely useful for any kind of local or remote file sync task from the command line or from scripts. This is not only because of the feature variety, but also because of its ubiquity. Most Linux distributions ship it by default and even macOS comes with an alternative implementation out-of-the-box (openrsync), that is fairly compatible (rsync is also available via homebrew).

I use it to publish this website and to create backups of my home directory onto an external hard drive.

When it comes to sharing data between my computers (on macOS, Linux and even sometimes Windows), I prefer using services that synchronize regular filesystem folders. I went through various services like Dropbox, OneDrive or Proton Drive, but eventually settled primarily on Syncthing, an open source alternative.
