如何用Percona XtraBackup進行MySQL從庫的單表備份和恢復
環境說明：
主庫:192.168.0.1
從庫1:192.168.0.2
從庫2:192.168.0.3
備份工具 : Percona xtrabackup version 2.4.8 based on MySQL server 5.7.13 Linux (x86_64) (revision id: 97330f7)
在主庫上建立chenfeng庫:
mysql> create database chenfeng;
Query OK, 1 row affected (0.08 sec)
mysql> use chenfeng
Database changed
mysql> create table duansf(id int (11),name varchar(10));
Query OK, 0 rows affected (0.14 sec)
mysql> insert into duansf values(1,'duansf');
Query OK, 1 row affected (0.01 sec)
mysql> insert into duansf values(2,'duansf');
Query OK, 1 row affected (0.01 sec)
只備份chenfeng庫的duansf表:
[root@localhost backup]# innobackupex --defaults-file=/etc/my.cnf --user=root --password=dsf0723 -S /tmp/mysql.sock --slave-info --safe-slave-backup --include=chenfeng.duansf /data/backup

IMPORTANT: Please check that the backup run completes successfully.
At the end of a successful backup run innobackupex
prints "completed OK!".

[root@localhost backup]#
innobackup部分引數解釋:
--slave-info會將master的binary log檔名和偏移量儲存到xtrabackup_slave_info檔案中
--slave-info,備份從庫, 加上 --slave-info 備份目錄下會多生成一個 xtrabackup_slave_info 檔案,
這裡會儲存主日誌檔案以及偏移, 檔案內容類似於:
CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000006', MASTER_LOG_POS=826270;
--safe-slave-backup會暫停slave的sql執行緒，待備份結束後再啟動
--include=REGEXP
對xtrabackup引數--tables的封裝，也支援ibbackup。備份包含的庫表，例如：--include="test.*"，意思是要備份test庫中所有的表。
如果需要全備份，則省略這個引數；如果需要備份test庫下的2個表：test1和test2,則寫成：--include="test.test1|test.test2"。也可以使用萬用字元，如：--include="test.test*"。
本例中只備份chenfeng庫下的duansf表，可以這麼寫--include=chenfeng.duansf
由於只備份了chenfeng庫的duansf表，所以我們在生成的時間目錄裡2017-10-15_20-33-07只看到了chenfeng資料夾.

解壓縮做恢復用:
恢復資料的時候，要經過prepare（recovery）和restore兩個步驟，
prepare匯出表步驟:

innobackup部分引數解釋:
--slave-info會將master的binary log檔名和偏移量儲存到xtrabackup_slave_info檔案中
--slave-info,備份從庫, 加上 --slave-info 備份目錄下會多生成一個 xtrabackup_slave_info 檔案,
這裡會儲存主日誌檔案以及偏移, 檔案內容類似於:
CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000006', MASTER_LOG_POS=826270;
--safe-slave-backup會暫停slave的sql執行緒，待備份結束後再啟動
--include=REGEXP
對xtrabackup引數--tables的封裝，也支援ibbackup。備份包含的庫表，例如：--include="test.*"，意思是要備份test庫中所有的表。
如果需要全備份，則省略這個引數；如果需要備份test庫下的2個表：test1和test2,則寫成：--include="test.test1|test.test2"。也可以使用萬用字元，如：--include="test.test*"。
本例中只備份chenfeng庫下的duansf表，可以這麼寫--include=chenfeng.duansf
由於只備份了chenfeng庫的duansf表，所以我們在生成的時間目錄裡2017-10-15_20-33-07只看到了chenfeng資料夾.

把chenfeng目錄打包放到/data/backup/bak目錄下:
[root@localhost 2017-10-15_20-33-07]# tar czvf chenfeng.tar.gz chenfeng
[root@localhost 2017-10-15_20-33-07]# mv chenfeng.tar.gz /data/backup/bak/
解壓縮做恢復用:
恢復資料的時候，要經過prepare（recovery）和restore兩個步驟，
prepare匯出表步驟:
[root@localhost backup]# innobackupex --defaults-file=/etc/my.cnf --user=root --password=dsf0723 -S /tmp/mysql.sock --apply-log --export /data/backup/2017-10-15_20-33-07
171015 20:49:32 innobackupex: Starting the apply-log operation
IMPORTANT: Please check that the apply-log run completes successfully.
At the end of a successful apply-log run innobackupex
prints "completed OK!".

mysql> select * from duansf;
Empty set (0.00 sec)
從xtrabackup備份裡恢復出duansf表資料:
刪除表：
mysql> drop table duansf;
Query OK, 0 rows affected (0.06 sec)
重建表結構:
mysql> CREATE TABLE `duansf` (
-> `id` int(11) DEFAULT NULL,
-> `name` varchar(10) DEFAULT NULL
-> ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Query OK, 0 rows affected (0.05 sec)
解除安裝表空間:
mysql> ALTER TABLE chenfeng.duansf DISCARD TABLESPACE;
Query OK, 0 rows affected (0.01 sec)
從備份裡恢復:
[root@localhost chenfeng]# cp /data/backup/2017-10-15_20-33-07/chenfeng/{duansf.ibd,duansf.cfg,duansf.frm} /usr/local/mysql/data/chenfeng
