innobackupex –user=root –password=123456 –no-timestamp /backup/mysql/full增加数据库中的数据
增加一个数据库db1, 并在db1中建立表t1(表的引擎为innodb),插入数据
MariaDB [(none)]> create database if not exists db1;
MariaDB [(none)]> use db1;
MariaDB [db1]> create table t1(id int,name varchar(20))engine=innodb;
MariaDB [db1]> insert into t1 values(1,‘aa‘);
增量备份第一次
[[email protected] ~]# innobackupex --user=root --password=123456 --no-timestamp --incremental-basedir=/backup/mysql/full --incremental /backup/mysql/01增加数据库中的数据
mysql -uroot -p123456 -e "insert into db1.t1(id,name)values(2,‘100‘);"增量备份第二次
[[email protected] ~]# innobackupex --user=root --password=123456 --no-timestamp --incremental-basedir=/backup/mysql/01 --incremental /backup/mysql/02模拟数据丢失，删除数据库中的所有内容
cd /var/lib/mysql/
rm -rf *
恢复完整备份
[[email protected] mysql]# innobackupex --user=root --password=123456 --apply-log --redo-only /backup/mysql/full/恢复第一次增量备份
[[email protected] mysql]# innobackupex --user=root --password=123456 --apply-log --redo-only /backup/mysql/full/ --incremental-dir=/backup/mysql/01恢复第二次增量备份
[[email protected] mysql]# innobackupex --user=root --password=123456 --apply-log /backup/mysql/full/ --incremental-dir=/backup/mysql/02将合并完的数据整体做一次apply-log
[[email protected] mysql]# innobackupex --user=root --password=123456 --copy-back /backup/mysql/full/设置权限
[[email protected] mysql]# chown -R mysql.mysql /var/lib/mysql/重启，看是否恢复成功
[[email protected] mysql]# systemctl restart mariadb
[[email protected] mysql]# mysql -uroot -p123456 -e "select * from db1.t1;"
