Your Mac has USB ports. They are probably USB-C ports that function as Thunderbolt and USB. You can get an adaptor to hook up an inexpensive hard disk for Time Machine use.
Word pros use File>Save As on a regular basis, altering the file name as they go: Important Document 01.docx, Important Document 02.docx, etc. When you have the final file, delete the temporary files. That way, you can only lose a little work instead of a whole document.
