As a Mac user I’ve always used Time Machine for local backups. The only issue is that it requires plugging a drive directly into your machine or buying an Apple Time Capsule. At $200–$400 that’s not a cheap option for NAS backups. So I set out to create my own DIY Time Capsule using a 3TB Hard Drive and a Raspberry Pi.
