摘要：背景一哥們發(fā)了個訴求，總覺得自己的服務(wù)器不安全，想搞個定時備份文件并發(fā)送到自己的郵箱實(shí)現(xiàn)代碼如下簡單說明打包文件這個實(shí)現(xiàn)比較初級，直接用命令進(jìn)行打包發(fā)送郵件這個就不說了，現(xiàn)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(fā)了個訴求，總覺得自己的服務(wù)器不安全，想搞個定時備份文件并發(fā)送到自己的郵箱

這個實(shí)現(xiàn)比較初級，直接用 shell 命令進(jìn)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(xiàn)成的模塊直接拿來用

加上日志，可以很清楚的讓我知道發(fā)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 15:01:05,401] INFO : send 20170414150001 backup files success

定時這個處理，直接使用 crontab 命令，創(chuàng)建個 backup_cron 文件，寫入

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

業(yè)務(wù)比較簡單，實(shí)現(xiàn)也比較簡單，沒啥可說的
