主要还是讲rsync的实践
上机实验
还有写一些脚本
下面是自动备份的脚本

#bak site and logs
ip= 'grep IPADDR /etc/sysconfig/network-scripts/ifcfg-eth0|cut -d = -f2'
mkdir /backup/$ip -p

cd /var/html && tar zcf /backup/$ip/www_$(date +%F).tar.gz ./www
cd /app && tar zcf /backup/$ip/logs_$(date +%F).tar.gz ./logs

#bak sys conf
cd / && tar zcf /backup/$ip/etc_$(date +%F).tar.gz ./etc
cd /server && tar zcf /backup/$ip/script_$(date +%F).tar.gz ./scripts
/bin/cp /var/spool/cron/root /backup/$ip/

#rsync data to bakserver
rsync -avzp /backup/ && rsync -avzp ./ rsync_backup@10.0.0.8::backup/$ip/ --password-file=/etc/
rsync.password> /dev/null 2>&1

#del data 7 days ago
find /backup -type f -name "*.tar.gz" -mtime +7|xargs rm -f
