GoKawiilDeveloper builds free 3-2-1 backup system across Linux devices to avoid cloud fees
A hobbyist developer detailed a personal project to implement the classic 3-2-1 backup strategy—three copies of data, on two different media, with one copy offsite—entirely using free, self-managed tools. The effort was sparked by frustration with paying for cloud storage like Google One just to access files they already own, and involved syncing a Minisforum mini-PC, a Lenovo laptop, external hard drives, and mobile devices.
