How to use Time Machine to back up your Mac to a Windows shared folder – macOS

The issue that makes Time Machine more difficult in terms of options for backup locations is that it requires use of Apple’s proprietary HFS+ filesystem. Although I’m certain the HFS+ features that Time Machine uses for file versioning and linking could be “mimicked” for use on other more open filesystems, the reality is that Apple chose HFS+ and supports that filesystem exclusively in Time Machine (in fact as of this writing Apple’s new APFS isn’t even supported for Time Machine backups as of yet).

  • Create a Windows share location
  • Make the remote share automatically mount
  • make Time Machine use the remote share and file
  • Check Time Machine

If unable to unmount drive on macOS

You can try booting from OS X recovery by holding CMD + R at the time of startup. Once booted from OS X recovery, select Terminal from the utilities and then at the unix prompt enter:

  • diskutil list
  • then press return and look for the disk identifier and enter the following command with the disk identifier

sudo diskutil unmountDisk /dev/(enter here disk identifier name)

  • Press return and enter your admin password if prompted. This should unmount all volumes of the physical drive.
  • If still the above method didn’t work, then the last option is to force the entire disk to unmount.
  • For that using the terminal application again, enter the following command:

sudo diskutil unmount force /dev/(enter here disk identifier name)

  • Then press return and enter the admin password if prompted. This will definetely unmount the entire disk and all its related volume.
