Mojave APFS Conversion
What's the best way to convert a backup volume to APFS in Mojave? I didn't see any evidence that SuperDuper! was going to do it for me.
Situation is:
What I ended up doing is running the Mojave installer while booted internal, to upgrade the external volume even though I'm just going to overwrite the results with SuperDuper! anyway. That worked (except for a boot-to-black-screen issue), but the computer is not usable while it is running the install. Also, there is some evidence that at the end it actually started up on the newly upgraded backup volume, which I did not want since there was danger of it synching out-of-date files. |

HFS boot volumes are not unsupported in Mojave...?
In Mojave, I'd just format it as APFS and recopy...

But will that create the Recovery volume?
I supposed worst case is I could create the Recovery volume in the APFS container using the command tools and copy from the internal drive. That's what I did for the pre-APFS backup drives. This is going to come up again when I upgrade the main machine to Mojave, which has a different backup drive. |

Yes, we create recovery volumes on APFS, copied from either HFS+ or APFS.

OK, I'll try it when I upgrade the main machine to Mojave.

I confirm that using SuperDuper! to clone an APFS start up drive to an empty APFS backup volume does create the APFS Recovery volume, along with the required Reboot and VM volumes. Yay.
Maintaining the Recovery HD partition on HFS backups was always a pain: first you had to manually create it, and then update it after upgrading to a new macOS version. And you couldn't use SuperDuper! regular erase-and-copy to update it because it would destroy the volume. Smart Update worked, but you had to manually mount and dismount the volumes from the command line. So automatic maintenance of the APFS Recovery volume is a win. |

3.3+ will also copy the recovery volume to HFS+ if the recovery partition is already on the destination...
