I believe that many people, like good VPS, use Putty to log in to Linux VPS because it is very compact and very convenient. However, if we change a computer, we will be very confused, because instead of simply copying it, we will have the previously saved server information. This should be complained about, hehe, it is not convenient enough.
Good VPSs are often replaced, so I record the backup process here so that I can find it when I forget it. If you don’t know, you can pay attention to it. For those who know, forget it~
