I have created two snapshots. When I click on this rollback disk, this prompt will be given. Now I want to change the windows server to linux. After I change to linux, I want to change to the current server. Is it enough to just click this to roll back the disk? Can it be restored to exactly what it is now? Can these configurations installed on the server be restored? Or only restore the contents of the hard drive?

A snapshot saves all the data of the server, including the status, at the time when the picture is taken. Everything will be back when you roll back the disk. Just like Ghost. Mirroring is similar to making a snapshot into a CD. You can put it into any virtual machine for recovery, but the snapshot can only roll back the disk.

    A snapshot is to take a snapshot of all the data files on your host at a certain moment. It is very vivid like taking a photo of the current host, so the data and configuration in your hard disk will be restored.

      All configuration information will be saved at the moment you create the snapshot~so it can be restored.
