Disable backup in VIM

Most modern Linux distributives set creation of backup files in vim by default. Probably it's useful in some particular cases (imho, it's better to make a backup for very important files yourself), but I lose my mind when I see the files like "textfile.txt~" everywhere I've edited a file.

To turn off the default backup add set nobackup to /etc/vim/vimrc or to your own vim config (in your home directory).
