Can you back to an APFS volume yet, or does it need to be HFS+?

  I was really surprised when APFS came out that it didn't support time machine. From the looks of this, it appears they're going to be able to write a new-style time machine on-top of APFS with the additions here. Interesting, over-due IMHO.

    I suspect they are waiting until they can migrate a time machine volume in one go (e.g. migrate the filesystem from HPFS with directory hard links to snapshots and a potential non-backup volume for other files). They have a lot of deep time machine integration in other parts of the system, so I suspect the staging of the projects means it is pushed off to sometime next year.

      Hearing about how snapshots work over the years during APFS sessions made me immediately think of 2007/2008 when they were describing the tech that eventually became Time Machine, but it wasn't a one click operation yet. As a perverse experiment, do we know what happens if you take an APFS SSD and try to format it as a TM volume? Guessing it's still not pretty despite the fact that HDD's under APFS are PNG, but directory hardlinks are gone. Does it work, but just fill up the disk - no deduping?

        Time Machine refuses to back up to APFS volumes at present.
