I’m still using this 30-year-old Linux backup tool, and you should too

Creating backups of my files has always been a hassle for me, and I’ve lost a lot of data on multiple occasions because of it. Turns out it’s because I was working hard instead of smart. Instead of copy-pasting folders between my PC and external drive, I could just use a tool that sends over only the file changes. It takes seconds to back up files with this approach and I can do it by running a single command.
