    I thought I read somewhere that if you use TimeMachine and include the VMs, then every time you use them they are backed up and if you have allocated a lot of space (e.g. 150G of my 512G SSD), then that means it is backing up the large 150G file every time.  Maybe I'm wrong?

    Just had the same problem. From my Macbook Pro went to Applications/Utilities/Disk Utility and set up two partitions on my external drive (1TB WD MyBook), 1 partition of 750GB formatted in exFAT so readable and writable by Mac & Windows, for photos and other data, another partition of just under 400GB formatted in Mac format for use by Time Machine for back ups. So far seems to be working fine...(touch wood).

    I'd check that exFAT partition on a Windows PC. Everytime I have used a Mac to format a partition exFAT when connecting that drive to a Windows PC Windows report the drive as Unformatted and need to be Initialized.

     

    If formatted exFAT on a Windows PC it then could be read and written to on either Mac or Windows.

    Macbook TimeMachine just finished backing up OK to the Mac partition on the external drive. Now plugged into the PC, only the exFat partition appears (as expected) as available. Copying 394 GB of photos to it - so far so good! Will know in about 5 hours time when it is finished if it worked or not!

     

    I read somewhere that it used to be a problem until quite recently that a drive formatted in exFat on a Mac couldn't be read/written by Windows but vice versa, exFat formatted on a PC was read/writeable by a Mac. This problem has now evidently been overcome.

     

    When I have funds available I shall set up a NAS drive but until then I'm banking on this method working!

    Glad to hear Apple straightened this out.
