So this week I have learned some things the hard way unfortunately. I have a T2.Medium EC2 Instance on a Ubuntu Server. I had decided to upgrade from Ubuntu 14.04 to 16.04
I am a newbie but have some experience in this. I thought I had done this right and I made a snap shot of my volume image weekly.
Well after I have no idea what exactly happened but I could not access or repair my WordPress website after I upgraded. So I thought I would open a new instance using my AMI snapshot. But this didn't work either as the new instance was also the new 16.04 ubuntu.....
So my question is I know the newer version is better for security reasons and more but
how do I make a complete back up of my system so this happens again I can revert back and work on the solution on the side until I am sure the new upgrade works 100%? And yes I know I should had done this the first time but lesson learned.
