+It is also possible to disable backups depending on the used method.
+The following code disables backups for the @option{su} and
address@hidden methods:
+
address@hidden
+(setq backup-enable-predicate
+      (lambda (name)
+        (and (normal-backup-enable-predicate name)
+             (not
+              (let ((method (file-remote-p name 'method)))
+                (when (stringp method)
+                  (member method '("su" "sudo"))))))))
address@hidden lisp
address@hidden ifset

 Another possibility is to use the @value{tramp} variable
 @ifset emacs
 @code{tramp-backup-directory-alist}.
