FTP script to automate file transfers to remote server

Below you will find a FTP script that will allow you to automate your files transfers without requiring any user input. The only problem with this method is you will be putting a username and password into the script file, but having a simple automated FTP file upload or FTP file download probably outweighs the drawback.

So to describe what this script does:
First the script will tar and zip all files and folders in the /var/log/ folder to the home directory of the user who runs the script. This will create a dated zip file in the user’s home folder who ran the script. Then it will FTP the files to the remote host. You can then add the script to a cron job to execute it everyday, week, hour, etc.
