What do we want? Time Machine backing up to APFS storage. When do we want it? Well, not quite yet.
Coming up to its 12th birthday, Time Machine backups have changed a great deal, but still rely on a feature almost unique to HFS+. What is their future?
Was WWDC a damp squib after all? With only one new unaffordable Mac announced, and more dreadful privacy dialogs on their way, you might think so.
Why measuring free and used disk space is not so simple in APFS, and which estimates you should trust.
With APFS, Time Machine underwent major change, to using snapshots to determine what to back up, rather than FSEvents. How well has this worked?
Adds support for local snapshot statistics, Dark Mode, fixes a bug, and is now notarized for your added security.
Detailed comparison of how Time Machine backs up HFS+ and APFS volumes, including its use of local snapshots, with diagrams.
When Time Machine backs up an APFS volume, it works quite differently from the way it did on HFS+. Explored here using log entries from Mojave.
Does APFS support its major new features – clones, snapshots, etc – yet, and how can you use them?
