(That’s when you select a volume, right-click, and choose Encrypt “Drive Name.”) Can I mount an APFS volume on a Mac running an older version of macOS than High Sierra? No! Apparently, an unexpected behavior in this first release is that using the Finder-based option to encrypt a mounted physical drive converts HFS+ drives to APFS without warning. Should I turn on encryption on an external HFS+ drive in High Sierra? But I can’t imagine that HFS+ will be unmountable in macOS anytime in the next three years, and it will very likely remain possible for years after that-although Apple could only support read-only HFS+ mounting at that point. It will likely provide more and more reasons in future releases for external drives to move to APFS, like requiring APFS drives for Time Machine. It would be foolhardy and it’s unnecessary. Not for many years, because of the tens of millions of systems out there.

If you clone your drive routinely, make a full clone before you upgrade, because otherwise you won’t be able to revert on an APFS drive to a previous system that uses HFS+. Bombich’s Carbon Copy Cloner, the other popular drive cloning app, has a release version that supports APFS, but notes (as Shirt Pocket does) that Apple has left some features undocumented, and has a long list of resources to read before upgrading. Dave Nanian of Shirt Pocket, makers of SuperDuper, has a beta release out (free to existing owners) that supports APFS volumes, but on his blog he advises general users against upgrading yet. Folks who develop cloning software for macOS are on the front lines of coping with these changes. Can I use cloning software to back up my drive? This will require wiping the drive, reformatting it, and then restoring the clone. You should make a clone (see next entry) if you want to have the option to revert back to Sierra.
