# This script is to take daily backup of mongodb
#**** Created by Manish Shrivastava ****
#=================================================
# Instead of backing up on set days this will check the time differences 
# between the last backup and the time the script running.

# Useful if you're backing up irregularly on a laptop

# A method to define the bubble sort
def bubble_sort(array)
  # condition: When array has more than one element
  if array.count > 1
    swap = true
    # Loop: Run until swap is true
    while swap
      swap = false
      # Loop: Run loop with array counts and swap if 
      (array.length-1).times do |z|
