Backup, restore, and transfer of the DHCP server for Windows Server 2012

The last time we introduced the DHCP server, this time to introduce you to the DHCP server backup, restore and transfer

First, the backup and restore of DHCP

Today's environment is: SERVER01 domain controller. SERVER02DHCP Server, server05 Client (user tests whether the DHCP server is working properly)

Example: Backup of the DHCP server database, restoring

First, let's install the DHCP service.

Open Server Manager, click Add Roles and Features

Once the authorization is complete, the DHCP server will work, and we'll test it with server05.

First, change the IP address of the server05 to auto-fetch.

We have shown that the DHCP server is working properly, so let's back up the DHCP server

Right-click the server, select Backup

Choose the location of the backup, here we use the default location, under C windows, System32 below, there is a DHCP folder under the backup, such as

After the backup is complete, we delete the newly created scope, simulate the accidental deletion, and test whether the restore was successful.

After we introduced the backup and restore, we are going through an experiment to introduce the migration of the server

Example: DHCP server migration, migrating a DHCP server from Server02 to Server01

Step 1: First of all we need to the migration of the server to make a backup, we will use just the backup to complete the experiment, first find the backup file, location is C:\Windows\System32\dhcp

Step 2: Copy the backup folder to Server01

In Server01, access the shared folder through remote access

After the server restore is complete, we will authorize the server

Right-click the server and select authorize
