(otherwise the files backed up in the specified directory
will keep their original filenames).
+Note that if you specify a relative path, the backup directory will be
+relative to the destination directory, so you probably want to specify
+either an absolute path or a path that starts with "../". If an rsync
+daemon is the receiver, the backup dir cannot go outside the module's path
+hierarchy, so take extra care not to delete it or copy into it.

dit(bf(--suffix=SUFFIX)) This option allows you to override the default
backup suffix used with the bf(--backup) (bf(-b)) option. The default suffix is a ~
if no -bf(-backup-dir) was specified, otherwise it is an empty string.
