this is the section for example.

if [[ "${CONFIG_mysql_dump_use_separate_dirs}" = "yes" ]]; then
            for db in "${CONFIG_db_month_names[@]}"; do
              echo "Monthly Backup of Database ( ${db} )"
              (shopt -s nullglob dotglob; f=("${CONFIG_backup_dir}/${subfolder}/${db}/${prefix}${db}_${date_stamp}_"[0-9][0-9]"h"[0-9][0-9]"m${midfix}${extension}${suffix}"); ((${#f[@]}))) && continue
              process_dbs "$subfolder" "$prefix" "$midfix" "$extension" "$rotation" "$rotation_divisor" "$rotation_string" 0 "$db"
              echo ----------------------------------------------------------------------
            done
          else
              echo "Monthly backup of databases ( ${CONFIG_db_month_names[@]} )."
              (shopt -s nullglob dotglob; f=("${CONFIG_backup_dir}/${subfolder}/${prefix}all-databases_${date_stamp}_"[0-9][0-9]"h"[0-9][0-9]"m${midfix}${extension}${suffix}"); ((${#f[@]}))) &&
                process_dbs "$subfolder" "$prefix" "$midfix" "$extension" "$rotation" "$rotation_divisor" "$rotation_string" 1 "${CONFIG_db_month_names[@]}"
              echo "----------------------------------------------------------------------"
          fi

config contains two values

# Backup directory location e.g /backups
#CONFIG_tmp_dir='/sql/tmp/'

# Backup directory location e.g /backups
#CONFIG_backup_dir='/mysql_backups/'
