Comment 3 for bug 1513433

Reopened Issue with weird situation:

When Table is create in '/var/lib/mysql_tablespaces':

mysql> CREATE TABLE `t2` (
    -> `c1` int(11) NOT NULL,
    -> PRIMARY KEY (`c1`)
    -> ) ENGINE=InnoDB DEFAULT CHARSET=latin1 DATA DIRECTORY='/var/lib/mysql_tablespaces';
Query OK, 0 rows affected (0.02 sec)

mysql> set tokudb_backup_dir='/home/tokubackupdir';
Query OK, 0 rows affected (2.57 sec)

The backup will copy t2.ibd:

root@percona-XPS-15:/home/tokubackupdir# ls mysql_data_dir_tablespaces/t1/
t1.ibd t2.ibd

But if you create table as:

CREATE TABLE `t2` (
  `c1` int(11) NOT NULL,
  PRIMARY KEY (`c1`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 DATA DIRECTORY='/home/datadir/'

Backup will missed t2.ibd.
