Active Directory Backup and Recovery (2)

One might ask, is there an active directory with so much data? In fact, if you just pay attention to the information displayed during the backup, then you will know that this backup includes three things: BOOT information, Active Directory information, and all files under the System32 folder, the largest is the System32 folder. So 537M is not surprising. OK, the backup is complete. So how do you recover if the domain controller is damaged? Next, I will see this. First of all, you have to reinstall the operating system. Since I am using a virtual machine, I just need to delete the previous changes. Hey, there is such a benefit to using a virtual machine. Whenever a physical machine can do this, it will be fine. Then press F8 at boot time:

Here, we have to choose, the seventh item: & ldquo; directory service restore mode (only for Windows domain controllers) & rdquo;, I really don't know if this sentence is Who is Microsoft looking for translation? I think the text in brackets should be translated as: "Only for restoring Windows domain controllers" is more appropriate. I don’t know how many people have been hurt. I have seen many networks. The administrator first promotes the server to a domain controller and then performs the recovery operation. In fact, everyone has forgotten that there is Active Directory information in the file we just backed up.

In the Windows login window, if your server is just a member server, enter the password of the local administrator. If it is a domain controller, enter the recovery password. what? What is the restore password? Take a look at my first post.

Continue to click "Start-Run", enter “Ntbackup”, and press Enter:

Don't choose the Backup Wizard again, use the “Restore Wizard (Advanced) )”:

Click "The next step" to come out as follows:

Right click on the "File" dialog box:

Click “File Catalog&rdquo ;:

Enter the location of the backup file, then make sure:

Then click “Next”:

If you confirm the above screen correctly, you can click “Complete & rdquo;:

Click on the warning window that appears & ldquo; OK & rdquo;:

This screen is similar to the backup screen? After a few minutes, you can complete it. After you finish, you will be asked to restart your computer. After rebooting, you will find that this member server has become a domain controller, and it is exactly the same as before.

2, Active Directory Recovery in a Multi-Domain Controller Environment

Someone may see this title and ask, how do you talk about recovery? Don't have to back up? Yes, if only the Active Directory information is indeed not backed up. why? I remember that I mentioned in the previous article that starting with the Windows 2000 domain, the multi-homed replication mechanism is used, that is, all Active Directory modifications will be copied to all domain controllers, so it is not necessary. Backed up. Just look at how to recover.
