import osimport time# 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 thatsource = [r'C:\Python\test']# 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 usingtarget_dir = r'C:\Python\test2\\'# 3. The files are backed up into a zip file.# 4. The name of the zip archive is the current date and timetarget = target_dir + time.strftime('%Y%m%d%H%M%S') + '.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))zip_command = r"""D:\Progra~1\7-Zip\7z.exe a %s %s""" % (target, ''.join(source))# Run the backupif os.system(zip_command) == 0:print 'Successful backup to', targetelse:print 'Backup FAILED'
