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).

- Make the remote share automatically mount
- make Time Machine use the remote share and file
- Check Time Machine
