如何从MySQL全备中恢复Innodb单表 - MySQL教程

1.The ibd file must be from a consistent backup with all insert buffer entries merged  and have no uncommitted transactions in order to not be dependent of the shared 2.tablespace ibdata. That is, shutting down with innodb_fast_shutdown=0. We’ll use XtraBackup to avoid the server shutdown.

3.You must not drop, truncate or alter the schema of the table after the backup has been taken.

The variable innodb_file_per_table must be enabled.

[root@test bin]# ./innobackupex --defaults-file=/service/mysql5.5/my.cnf  --export /backup/5.5/
