增量備份

 

[root@vSWHVMSDBTE01 bak]# innobackupex --socket=/var/lib/mysql/mysql.sock -u root -p Oracle123$ /data/bak/ --no-timestamp

[root@vSWHVMSDBTE01 bak]# innobackupex --socket=/var/lib/mysql/mysql.sock -u root -p Oracle123$ --incremental /data/bak_incr/ --incremental-basedir=/data/bak --no-timestamp

 

增量恢復

[root@vSWHVMSDBTE01 lib]# service mysqld stop

[root@vSWHVMSDBTE01 lib]# mv /var/lib/mysql /var/lib/mysql_old

[root@vSWHVMSDBTE01 lib]# mkdir /var/lib/mysql

[root@vSWHVMSDBTE01 lib]# chown -R mysql.mysql mysql

恢復全備份Read only模式

[root@vSWHVMSDBTE01 bak]# innobackupex --apply-log --redo-only /data/bak

最次一次增量恢復不需要read only

[root@vSWHVMSDBTE01 bak_incr]# innobackupex --apply-log /data/bak --incremental-dir=/data/bak_incr

恢復全備份，回滾未提交事務

[root@vSWHVMSDBTE01 bak_incr]# innobackupex --apply-log /data/bak

[root@vSWHVMSDBTE01 mysql]# innobackupex --copy-back /data/bak

[root@vSWHVMSDBTE01 mysql]# chown -R mysql.mysql /var/lib/mysql

[root@vSWHVMSDBTE01 mysql]# service mysqld start
