+Borg always stores all file paths normalized, with the first part equal to the

+``/absolute/path`` as root, the paths going into the matcher will start with

+``/absolute/path/logs/*.log``, the pattern ``logs/*.log`` would not match; you
+must use ``absolute/path/logs/*.log`` or ``**/logs/*.log`` (using ``sh``
+patterns). The pattern ``/absolute/path/logs/*.log`` will also match, since
