【Linux中Mysql数据库之定时备份】

一、Linux下面Mysql数据库定时备份脚本

[root@node1 ~]# vi backupMysql.sh
#!/bin/bash
# Name:bakmysql.sh
# This is a ShellScript For Auto DB Backup and Delete old Backup

#backup dir
backupdir=/home/mysqlbackup
#filename
time=`date +%Y_%m_%d_%H_%M_%S `
#mysql dbname
db_name=test
#mysql username
db_user=root
#mysql passwd
db_pass=123456

#begin backup
mysqldump -u $db_user -p$db_pass $db_name | gzip > $backupdir/$db_name$time.sql.gz
#end backup

#delete the old backup the day before 10 days
find $backupdir -name $db_name"*.sql.gz" -type f -ctime? +10? -exec rm -rf {} \;

实际应用中数据量非常大，可以进行增量备份；也可以进行物理备份即拷贝文件目录。
