摘要：背景一哥們發了個訴求，總覺得自己的服務器不安全，想搞個定時備份文件并發送到自己的郵箱實現代碼如下簡單說明打包文件這個實現比較初級，直接用命令進行打包發送郵件這個就不說了，現成的模塊直接拿來用日志記錄加上日志，可以很清

一哥們發了個訴求，總覺得自己的服務器不安全，想搞個定時備份文件并發送到自己的郵箱

這個實現比較初級，直接用 shell 命令進行打包

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

這個就不說了，現成的模塊直接拿來用

加上日志，可以很清楚的讓我知道發送情況如下，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

定時這個處理，直接使用 crontab 命令，創建個 backup_cron 文件，寫入

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

業務比較簡單，實現也比較簡單，沒啥可說的
