.. important:: The capabilities of the ``setcap`` command only applies to this
specific copy of the restic binary. If you run ``restic self-update`` or
in any other way replace or update the binary, the capabilities you added
above will not be in effect for the new binary. To mitigate this, simply
run the ``setcap`` command again, to make sure that the new binary has the
same and intended capabilities.
From now on the user ``restic`` can run restic to backup the whole
system.
