简单备份文件并发送到指定邮箱

摘要：背景一哥们发了个诉求，总觉得自己的服务器不安全，想搞个定时备份文件并发送到自己的邮箱实现代码如下简单说明打包文件这个实现比较初级，直接用命令进行打包发送邮件这个就不说了，现成的模块直接拿来用日志记录加上日志，可以很清

        logger.error("send {} failed {}".format(name, e))
        sendmail()


if __name__ == "__main__":
    sendmail()

这个实现比较初级，直接用 shell 命令进行打包

def zip_files():
    """zip files"""
    os.system("tar -cjf {} -C {} data".format(zip_path, base_path))

这个就不说了，现成的模块直接拿来用

加上日志，可以很清楚的让我知道发送情况如下，示例如下：

[2017-04-14 00:00:03,251] INFO : send 20170414000001 backup files success
[2017-04-14 03:00:02,620] INFO : send 20170414030001 backup files success
[2017-04-14 06:00:02,406] INFO : send 20170414060001 backup files success
[2017-04-14 09:00:02,349] INFO : send 20170414090001 backup files success
[2017-04-14 12:00:02,299] INFO : send 20170414120001 backup files success
[2017-04-14 15:01:04,696] ERROR : send 20170414150001 failed [Errno 110] Connection timed out
[2017-04-14 15:01:05,401] INFO : send 20170414150001 backup files success

定时这个处理，直接使用 crontab 命令，创建个 backup_cron 文件，写入

0 */3 * * *  python /root/xxxxx/backup.py

业务比较简单，实现也比较简单，没啥可说的
