What makes you think a server was involved here? It was a local repository, evidenced by the reporter’s bewilderment that files can be deleted without going to the Recycle Bin first. Which tells us that in addition to VCS, they were unfamiliar with Windows as well.
Hobbyist myself so no worries! Git is one example of source control / version control software. You normally have your local working copy of a repository and then a remote where you push your changes when they are finished or to share them with others.
