本文介绍如何使用Python的zipfile模块实现文件备份及压缩，并利用Windows的任务计划程序进行定时任务调度。此外，还提供了使用CMD脚本及robocopy命令备份文件的方法。

1.使用Python压缩文件并另存

 1 import zipfile, os
 2 
 3 #备份文件ZIP格式： folder 目标文件夹 ； Targetfolder：另存地址
 4 def backuptozip(folder, Targetfolder):
 5     if Targetfolder=="":
 6         Targetfolder=folder
 7     folder = os.path.abspath(folder)
 8     number = 1
 9     while True:
10         zipFilename = os.path.basename(folder) + "_" + str(number) + '.zip'
11         newzip=Targetfolder+zipFilename
12         if not os.path.exists(newzip):
13             break
14         number = number + 1
15 
16     print('creating...' + (newzip))
17     backupzip = zipfile.ZipFile(newzip, 'w')
18     newfolder = os.path.basename(folder)
19     for foldername, subfolders, filenames in os.walk(folder):
20         print("adding file in ..." + foldername)
21         cc = len(folder)
22         cnewfolder = newfolder + foldername[cc:]
23         backupzip.write(foldername, cnewfolder)
24         for filename in filenames:
25             newBase = newfolder + '_'
26             if filename.startswith(newBase) and filename.endswith('.zip'):
27                 continue
28             cnewfile = cnewfolder +"\\"+ filename
29             backupzip.write(os.path.join(foldername, filename), cnewfile)
30     backupzip.close()
31     print('Done.')
32 
33 backuptozip("C:\\Users\\xxx\\OneDrive\\","")

2.使用CMD脚本 - robocopy 命令备份并存储日志

robocopy Z:\ E:\ShareBackup /z /is /e >> E:\ShareBackuplog\%date:~0,4%%date:~5,2%%date:~8,2%_log.txt

（更多robocopy 参数使用可参考 http://www.cnblogs.com/xinyuxin912/archive/2013/07/10/3181564.html）　

3.通过window自带任务计划程序定时调度
