Testing out snapshots in Apple’s next-generation APFS file system

Back in June, Apple announced its new upcoming file system: APFS, or Apple File System. There was no mention of it in the WWDC keynote, but devotees needed no encouragement. They picked over every scintilla of data from the documentation on Apple’s developer site, extrapolating, interpolating, eager for whatever was about to come. In the WWDC session hall, the crowd buzzed with a nervous energy, eager for the grand unveiling of APFS. I myself badge-swapped my way into the conference just to get that first glimpse of Apple’s first original filesystem in the 30+ years since HFS.
