NCP: path in nc-backup.sh

Hi,
in the file nc-backup.sh there is from line 81 the tar command line. There are some –exclude options, but there are options with
--exclude "$data/..."
and
--exclude "nextcloud/data/..."

Shouldn’t it be always the first path name $data? If one has configured nc-datadir, then “nextcloud/data/…” will be no valid directory?
