In MySQL 5.6 Oracle introduced a Transportable Tablespace feature (copying tablespaces to another server) and Percona Server adopted it for partial backups which means you can now take individual database or table backups and your destination server can be a vanilla MySQL server. Moreover, since Percona Server 5.6, innodb_import_table_from_xtrabackup is obsolete as Percona Server also implemented Oracle MySQL’s transportable tablespaces feature which as I mentioned gives you the ability to copy tablespace (table.ibd) between servers. Let me demonstrate this through one example where I am going to take partial backup of selective tables instead of an entire MySQL server and restore it on a running MySQL …

There is one new feature in MySQL 5.6 that didn’t get the attention it deserved (at least from me ) : “DATA DIRECTORY” for InnoDB tables.

This is implemented since MySQL 5.6.6 and can be used only at the creation of the table. It’s not possible to change the DATA DIRECTORY with an ALTER for a normal table (but it’s in some case with partitioned ones as you will see below). If you do so, the option will be just ignored:

mysql> CREATE TABLE `sales_figures` (
    ->   `region_id` int(11) DEFAULT NULL,
    ->   `sales_date` date DEFAULT NULL,
    ->   `amount` int(11) DEFAULT NULL
    -> ) ENGINE=InnoDB DEFAULT CHARSET=latin1
    -> DATA DIRECTORY = '/tb1/';
Query OK, 0 rows affected (0.11 sec)
mysql> alter table sales_figures engine=innodb data directory='/tb2/';
Query OK, 0 rows affected, 1 warning (0.21 sec)
Records: 0  Duplicates: 0  Warnings: 1
mysql> show warnings; …
