I have been honoured this year to be invited to present at MacSysAdmin Online 2021, talking about Time Machine.

You can watch my presentation and download my slides from here, where you’ll also find plenty of even better presentations.

My teaser runs:
By macOS Catalina, Time Machine to HFS+ disks had reached a crisis. This talk explains those problems, and how backing up to APFS has breathed new life into one of the most important features of macOS.

Here’s a small collection of links to articles here which you may also find useful on this subject.
