Does APFS support its major new features – clones, snapshots, etc – yet, and how can you use them?

This new version lets you select which log file to analyse, and to add custom processes to examine within log files. Lots of power with elegant simplicity.
For now, Time Machine can’t back up to an APFS volume. There are many problems with backing up APFS to HFS+, though. Time Machine needs to be revised.
Should fix a bug in which T2M2 reports an error message rather than completing an analysis of Time Machine backups.
You may still have plenty of space on your backup volume, but if it has millions of files and hard links from years of backups, it will be very slow. Here’s how to fix that.
The High Sierra upgrade did not go well for many users. Here are some of the reasons why macOS 10.13 is currently a lemon.
Time Machine diagnostics now available for Sierra, and (in beta) for High Sierra.
Explains how Time Machine knows what to back up, why it performs deep event scans, and how that system is different from HFS+ journaling.
A strange problem with backups that start, but fail to complete successfully, apparently because of duplicate filenames. T2M2 to the rescue, bringing some important lessons.
Scheduling background activities like making backups has moved from cron to launchd, and now to a more complex system. This has reduced the reliability of macOS and made it harder to support.
