Making backups (with rsync)

This is the most important work system administrators have to do. In this section, we will learn about making backups using rsync. The rsync command is used for copying files and directories locally, as well as remotely, and performing data backups using rsync. For that, we are going write a script called take_backup.py and write the following code in it:

import os
import shutil
import time
from sh import rsync
def check_dir(os_dir):
            if not os.path.exists(os_dir):
                        print (os_dir, "does not exist.")
                        exit(1)
def ask_for_confirm():
            ans = input("Do you want to Continue? yes/no\n")
            global con_exit
            if ans == 'yes':
                        con_exit = 0
                        return con_exit
            elif ans == "no":
                ...
