# 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')

# Create the subdirectory if it isn't already there
if not os.path.exists(today):
	os.mkdir(today) # make directory
	print 'Successfully created directory',today

# The name of the zip file
target=today+os.sep+now+'.zip'

# 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))

# Run the backup
