+
+Emacs has a built-in backup system, but it does not backup on each
+save. It can be made to, but that makes saving really slow (and the
+UI unresponsive), especially for large files.
+
+Fortunately, Emacs has asynchronous processes.
+
+To enable for all files -
+  `(add-hook 'after-save-hook #'async-backup)`
+  
+To enable for a specific file -
+  `M-x add-file-local-variable RET eval RET (add-hook 'after-save-hook #'async-backup nil t) RET`
