删除old文件

vi /tmp/rmBackup.sh

#!/bin/sh

# Name:rmBackup.sh

# PS:Delete old Backup.

# 定义备份目录

dataBackupDir=/tmp/mysqlbackup

# 删除mtime>2的日志备份文件

find $dataBackupDir -name "mysql_*.gz" -type f -mtime +2 -exec rm {} \; > /dev/null 2>&1

同步备份到备份服务器

vi /tmp/rsyncBackup.sh

#!/bin/sh

# Name:rsyncBackup.sh

#定义数据库备份目录

dataBackupDir=/tmp/mysqlbackup/

# 定义备份服务器上存放备份数据的目录

backupServerDir=/root/mysqlbackup/

# 定义备份服务器

backupServer=172.16.107.133

# 同步备份文件到备份服务器

rsync -a --delete $dataBackupDir -e ssh $backupServer:$backupServerDir > /dev/null 2>&1

恢复服务器

全部恢复

mysqldump --user=root -p --all-databases > /backup/mysql.sql

DB恢复

/usr/local/mysql/bin/mysql -uroot -pUserPWD db_name < db_name.sql

增量恢复

1.对于任何可适用的更新日志，将它们作为 mysql 的输入

% ls -t -r -1 HOSTNAME-bin* | xargs mysqlbinlog | mysql -uUser –pUserPWD

2.一般恢复

/usr/local/mysql/bin/mysqlbinlog mysql-bin.000052 | mysql -uUser -pUserPWD
