Question

i have a question and that is the title, from what i know they are something or someplace to store files over the internet so you can retrieve it from anywhere as long as you have internet, but why are there so many types of them? if all they do is the same thing that is to store files and then also allow you to retrieve them.

Answer 1

There not backup systems, they’re version controls.

You can use Git or mercurial on your computer without any internet connection. There are two main ideas behind it :

• Track history of what you’ve done (finding what change introduced a bug, undo a crappy change…)
• Work in team : how to be sure that everybody has the newest version of a file without risking to overwrite your own changes
