Zabbix备份数据文件

mysql自带的工具mysqldump，当数据量大了之后进行全备所花的时间比较长，这样将会造成数据库的锁读、从而zabbix服务的监控告警不断，想着做下配置文件的备份、刚好有这么个脚本、满足了需求。

后续会使用xtrabckup来进行完成备份，执行这个脚本所花时间不过几秒

加入计划任务、每天可以执行一次

[root@Zabbix-Server zabbix]# crontab -l|tail -
#Q--/
  * * * /etc/zabbix/zabbix-datafile-bak.sh mysqldump

重启下计划任务服务

/sbin/service crond restart
