MySQL全备及备份文件删除脚本

1.数据库全备

#!/bin/sh
v_user="root"
v_password="mysql"
backup_date=`date +%Y%m%d%H%M`

MysqlDir=/usr/local/mysql/bin

BackupDir=/data/mysql
Full_Backup=$BackupDir/Full_backup
mkdir -p $Full_Backup/$backup_date

echo '========='$(date +"%Y-%m-%d %H:%M:%S")'=========='"BEGIN">>$Full_Backup/$backup_date/full_backup.log
$MysqlDir/mysqldump -u$v_user -p$v_password --single-transaction --flush-logs  --all-databases>$Full_Backup/$backup_date/full_backup.sql

gzip $Full_Backup/$backup_date/full_backup.sql
echo '=========='$(date +"%Y-%m-%d %H:%M:%S")'=========='"FINISH">>$Full_Backup/$backup_date/full_backup.log

 

2.删除30天前备份文件

echo "`date +'%Y-%m-%d %H:%M:%S'` remove full_backup_files 30 days ago"|tee -a /data/mysql/remove_backup_files.log && find /data/mysql/Full_backup -name "full_backup.*" -mtime +30 -type f| tee -a /data/mysql/remove_backup_files.log | xargs rm -f 2>&1

 

3.定时任务设置

#每天1点定时执行全库备份
0 1 * * * /data/mysql/full_backup.sh

#每天1点30分定时删除30天前备份文件
30 1 * * * /data/mysql/remove_backup_files.sh
