You are so wrong at so many levels.... I sincerily hope that you might never find how wrong you are.

What you describe is the ideal society based in merit and where everyone gets a chance.
The reality is completely different. The reality will show you that some people are more equal than others. That sometimes it is better to "sell" your achievements than actually work to achieve something.

I believe you are misusing the concept of Backup.
When you backup something, you are not supposed to change it. I you do, then it will be another version and another file. Otherwise you won't be able to access a past version and that might be the version you need.

I you want a remote storage, then go with some USB disk or a more advanced data storage equipment.
