MacVoices #21108: Mark Fuccio Talks Snapshots, Time Machine, and Big Sur Mark Fuccio has a long history with snapshot technology, long before it came to the Mac. He details that history and gives us some insights into how they came to be, what they are, and why you should care. If you are confused, Mark provides a simple analogy that helps clarify things, explains how Time Machine in Big Sur is a change from previous iterations and why it is better, and answers questions about what they can and can’t do.
