利用ZRM(lvm+binlog方式)进行数据库备份及还原

安装ZRM：

[root@master ~]# yum -y install perl-DBI perl-DBD-MySQL perl-XML-Parser
[root@master ~]# yum localinstall MySQL-zrm-3.0-1.noarch.rpm
[root@master ~]# ls /etc/mysql-zrm/
mysql-zrm.conf  mysql-zrm-release  mysql-zrm-reporter.conf  RSS.header
[root@master mysql-zrm]# ln -s /usr/local/mysql/bin/* /usr/bin/

创建备份用户并授权

mysql>  grant select, insert, update, create, drop, reload, shutdown, alter, super, lock tables, replication client on *.* to 'backup-user'@'localhost' identified by 'redhat';
Query OK, 0 rows affected (0.01 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

创建备份目录

[root@master ~]# mkdir /backup/zrm -pv
[root@master mysql-zrm]# mkdir full

修改配置文件：

[root@master full]#  egrep -v '^#|^$' mysql-zrm.conf
backup-level=0
backup-mode=raw
lvm-snapshot=100M
snapshot-plugin="/usr/share/mysql-zrm/plugins/lvm-snapshot.pl"
backup-type=regular
destination=/backup/zrm
retention-policy=1W
compress=1
compress-plugin=/usr/bin/gzip
all-databases=1
user="backup-user"
password="redhat"
host="localhost"
socket=/tmp/mysql.sock
mysql-binlog-path="/mydata/data"
mailto="mysqldba@sanyu.com"

手工执行备份：

先用全备还原

[root@master mysql-zrm]# mysql-zrm --action restore --backup-set mybak-2013-08-27 --source-directory /backup/zrm/mybak-2013-08-27/20130827012922/

此时shop库已还原，但是全备后插入的记录（week0）还未恢复用增量备份还原：

[root@master mysql-zrm]# mysql-zrm --action restore --backup-set mybak-2013-08-27 --source-directory /backup/zrm/mybak-2013-08-27/20130827013928/

至此数据已找回，增备到误操作期间的数据需借助binlog人工恢复，这里不再演示
