刪除old文件

vi /tmp/rmBackup.sh

#!/bin/sh

# Name:rmBackup.sh

# PS:Delete old Backup.

# 定義備份目錄

dataBackupDir=/tmp/mysqlbackup

# 刪除mtime>2的日志備份文件

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

同步備份到備份服務(wù)器

vi /tmp/rsyncBackup.sh

#!/bin/sh

# Name:rsyncBackup.sh

#定義數(shù)據(jù)庫備份目錄

dataBackupDir=/tmp/mysqlbackup/

# 定義備份服務(wù)器上存放備份數(shù)據(jù)的目錄

backupServerDir=/root/mysqlbackup/

# 定義備份服務(wù)器

backupServer=172.16.107.133

# 同步備份文件到備份服務(wù)器

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

恢復(fù)服務(wù)器

全部恢復(fù)

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

DB恢復(fù)

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

增量恢復(fù)

1.對于任何可適用的更新日志，將它們作為 mysql 的輸入

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

2.一般恢復(fù)

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

定制任務(wù)

#crontab –e

10 4 * * 1-6 root /tmp/mysql_daily_bak.sh #禮拜一到禮拜六運(yùn)行每天備份腳本

10 4 * * 0 root /tmp/mysql_full_bak.sh #禮拜天執(zhí)行全備份的腳本
