Relive the old days of Apples's networked Time Capsule using a much more affordable SBC and your choice of external storage device

If you use a Mac, you’ve likely seen the little Time Machine icon in your menu bar and ignored it until disaster struck. For years, I relied on external drives or my primary server for backups, but I wanted something more flexible, inexpensive, and energy-efficient. That’s when I turned to a Raspberry Pi. With a bit of setup and the right software, I created a network Time Machine backup solution that just works quietly in the background.
