Use ``--read-data-subset=NS`` to check a randomly chosen subset of the repository pack files.
It takes one parameter, ``NS``, where 'N' is a whole number representing file size and 'S' is the unit
of file size (B/K/M/G/T) of pack files to check. Behind the scenes, the specified size will be converted
to percentage of the total repository size. The behaviour of the check command following this conversion
will be the same as the percentage option above. For a file size value the following command may be used:
.. code-block:: console
$ restic -r /srv/restic-repo check --read-data-subset=50M
