Due to my lack of strength, I was unable to determine whether the problem was in the process of troubleshooting. I was afraid that the environment would be messed up, so I took a snapshot by the way today, as I learned how to make a backup.
Many times you encounter some problems on the server, and you are not sure if you are, you can create this snapshot, and then you can return to the origin.
Server system snapshot
Environment: windows sever 2012 r2

When it is opened to backup, as shown in the figure below, it means that this function has not been installed

Backup depends on your own needs. I am here for a one-time backup, because I encountered some problems myself, I thought of backup.
Since the data is relatively large, I only plan to back up what I want to make before backing up. This can be done by looking at my own resource backup.
Then, click Next, and here, I chose to back up only the c drive, and the c drive can also choose which one to back up

Next step
Click on the backup to start, the process is relatively long, just wait
