How to Backup to Amazon S3 from Debian Linux

Hello everyone, welcome to Linux Tutorial Blog. Today I am going to show you how I backup to Amazon S3 from Debian Linux. On my previous tutorial, I have shown the similar tutorial to backup to Amazon S3 using third party software called Syncovery on a Linux Server. But today, we will not use any graphical application like Syncovery. We will backup to Amazon S3 using AWS CLI. AWS CLI (Command Line Interface) is a free command line program to communicate with Amazon AWS Console.
