How does the win7 computer automatically back up files when it is shut down?

            What is the most important thing in the computer? It is not the system. It is the file information stored in the computer. It can be not only our personal data, but also our work materials. Anyway, they are stored in our computer. Some use, lost or accidentally lost, it is a pity. However, some friends found that their computer has some faults, such as restarting the computer, or suddenly turned on the next day and found that the information inside is gone. In fact, if we can back up the computer files every time we shut down, then this situation will not appear again. Below, Xiaobian will introduce how the win7 32-bit system realizes the automatic backup of the data before shutdown.
First, let's assume a directory that needs to be backed up, for example, e:\\My working file, then we need to create a shortcut on the desktop, so that each compressed backup can be implemented automatically, just click Just press the button. In general, the full path of Winrar.exe is "E:\\program files\\WinRAR\\winrar.exe", so the path that we should fill in the current compressed file is E:\\Program Files\\WinRAR\\WinRAR.exe" ; ue:\\我工作.rar e:\\我工作–ioff.
The –ioff here means that the shutdown operation is automatically executed at the end. After setting the shortcut, we only need to associate a shortcut key. You only need to press this shortcut key to save the file every time you shut down. The backup is gone.
