in the meantime you can set a backup program to copy the original file to a 3rd folder specified through it
this is what I do: use syncback pro to make a copy of the original file multiple times a day (I use the mirroring option), the destination folder is in a gdrive/mega/dropbox/etc location in my hardisk
alternatively, you can also set up symbolic links to virtually make the original SB folder be located elsewhere e.g., gdrive, dropbox, etc
