# 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
# 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
# 3. The files are backed up into a zip file.
# 4. The current day is the name of the subdirectory in the main directory
today = target_dir + time.strftime('%Y%m%d')
# The current time is the name of the zip archive
now = time.strftime('%H%M%S')

if not os.path.exists(today):
　　os.mkdir(today) # make directory

# 5. We use the zip command (in Unix/Linux) to put the files in a zip archive

# Run the backup
if os.system(zip_command) == 0:
