Net-SSH and Net-SFTP

Hello readers!
This post is all about the power of Ruby.
After the day full of work I need to take the backup of my work there on remote as well as on my local machine.
Ruby Scripting helps the way out in a beautiful manner. There are two modules Net::SSH and Net::SFTP available at RUBY FORGE which can add a lots of more geek functionalities to your daily routine. One of them has relaxed me a lot.
Here I am going to explain a small n great use of Net::SSH and Net::SFTP.
-----------------------Pre-Requisites------------------------
To use this functionality from your local machine u will have to install ruby on your local machine.
After that install these two modules simply using Ruby GEM as follows...

1.) $ gem install net-ssh
2.) $ gem install net-sftp

after installation write the following code and save it as a ruby file say "backup.rb"
here is the code for "backup.rb"

#----------------BACKUP YOUR DATA ON LOCAL MACHINE--------------#
require 'net/ssh'
require 'net/sftp'
#----------------CONNECTION PARAMETERS--------------------------#
#... If u wanna use the default connection parameters then set the $default variable to "y" and
#... set the default values for $host,$username,$password variables in following elsif block.
#... Or Set $default to "n" to provide the connection parameters dynamically.
$default = "n"
if $default == "n"
print " Host : "
$host = gets().chop
print "Username : "
$username = gets().chop
print "Password : "
$password = gets().chop
elsif $default == "y"
$host = "localhost"
$username = "user"
$password = "pass"
end
#----------------TO BE MODIFIED AS PER NEED-----------------------#
$file_path = "exe/"
$file_exist = "temp1"
$download_path = "c:/test_backup/"
#-----------------------------------------------------------------#
time_now = Time.now()
$file_new = $file_exist + "_" + time_now.strftime("%a_%b_%d_%Y_%H_%M_%S") + ".tar.gz"
#------------------------NET::SSH----------------------------------#
Net::SSH.start($host, $username, $password) do ¦session¦
   shell = session.shell.open
   puts "SHELL IS RUNNING..."
   shell.tar "-czf " + $file_path + $file_new + " " + $file_path + $file_exist
   puts $file_new + " is successfully created "
   shell.exit
   sleep 0.5
   $stdout.print shell.stdout while shell.stdout?
   session.loop
end
#------------------------NET::SFTP----------------------------------#
Net::SFTP.start($host, $username, $password) do ¦sftp¦
   sftp.get_file $file_path + $file_new, $download_path + $file_new
end
