Python/CMD 文件备份

1.使用Python压缩文件并另存

 import zipfile, os

 #备份文件ZIP格式： folder 目标文件夹 ； Targetfolder：另存地址
 def backuptozip(folder, Targetfolder):
     if Targetfolder=="":
         Targetfolder=folder
     folder = os.path.abspath(folder)
     number = 1
     while True:
         zipFilename = os.path.basename(folder) + "_" + str(number) + '.zip'
         newzip=Targetfolder+zipFilename
         if not os.path.exists(newzip):
             break
         number = number + 1

     print('creating...' + (newzip))
     backupzip = zipfile.ZipFile(newzip, 'w')
     newfolder = os.path.basename(folder)
     for foldername, subfolders, filenames in os.walk(folder):
         print("adding file in ..." + foldername)
         cc = len(folder)
         cnewfolder = newfolder + foldername[cc:]
         backupzip.write(foldername, cnewfolder)
         for filename in filenames:
             newBase = newfolder + '_'
             if filename.startswith(newBase) and filename.endswith('.zip'):
                 continue
             cnewfile = cnewfolder +"\\"+ filename
             backupzip.write(os.path.join(foldername, filename), cnewfile)
     backupzip.close()
     print('Done.')

 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
