# 1. The files and directories to be backed up are specified in a list.
# source = ['/home/swaroop/byte', '/home/swaroop/bin']
# If you are using Windows,use source = [r'C:\Documents', r'D:\Work'] or something like that
source = [r'D:\myLab\python']

# 2. The backup must be stored in a main backup directory
# target_dir = '/mnt/e/backup/' # Remember to change this to what you will be using
target_dir = r'D:\myLab'

# 3. The files are backed up into a zip file.
# 4. The name of the zip archive is the current date and time
#target = target_dir + time.strftime('%Y%m%d%H%M%S') +'.zip'
# Windows Winrar
target = target_dir
fileName = time.strftime('%Y%m%d%H%M%S') +'.rar'

# 5. We use the zip command (in Unix/linux) to put the files in a zip archive
# zip_command = "zip -qr '%s' %s" % (target, ''.join(source))
zip_command = "winrar a %s %s %s" % (fileName, ' '.join(source), target)

# Windows Winrar

# Run the backup
print 'Zip_command is:', zip_command
print os.system('dir echo. & pause')

if os.system(zip_command) == 0:
    print 'Successful backup to', target
else:
    print 'Backup FAILED'
在Windos下可以压缩，但是无法指定将压缩文件转存在特定的目录下
