Windows 2000 Backup
can back up and restore Active Directory on Windows 2000 domain controllers. You
can perform a backup operation while the domain controller is online. You can
perform a restore operation only when the domain controller is booted into
Directory Services Restore mode (by pressing the F8 key when the server is
booting).
How to Back Up the
System State on a Domain Controller
-
Click Start, point to Programs,
point to Accessories, point to System Tools, and then click Backup.
- Click the
Backup tab.
- Click to
select the System State check box. (All of the components to be backed up are
listed in the right pane. You cannot individually select each item.)
NOTE: During the system state backup, you must select to back up the Winnt\Sysvol
folder. You must also select this option during the restore operation to have
a working sysvol after the recovery.
The following
information applies only to domain controllers. You can restore member servers
the same way, but in normal mode.
If any of the following conditions are not met, the system state is not
restored. Backup attempts to restore the system state, but does not succeed.
| The drive
letter on which the %SystemRoot% folder is located must be the same as when it
was backed up. |
| The %SystemRoot%
folder must be the same folder as when it was backed up.
|
| If sysvol or
other Active Directory databases were located on another volume, they must
exist and have the same drive letters also. The size of the volume does not
matter. |
How to Restore the
System State on a Domain Controller
-
To restore the system state on a
domain controller, first start the computer in Directory Services Restore
Mode. To do so, restart the computer and press the F8 key when you see the
Boot menu.
- Choose
Directory Services Restore Mode.
- Choose the
Windows 2000 installation you are going to recover, and then press ENTER.
- At the
logon prompt, supply the Directory Services Restore mode credentials you
supplied during the Dcpromo.exe process.
- Click OK to
acknowledge that you are using Safe mode.
- Click
Start, point to Programs, point to Accessories, point to System Tools, and
then click Backup.
- Click the
Restore tab.
- Click the
appropriate backup media and the system state to restore.
NOTE: During the restore operation, the Winnt\Sysvol folder must also be
selected to be restored to have a working sysvol after the recovery process.
Be sure that the advanced option to restore "junction points and data" is also
selected prior to the restore. This ensures that sysvol junction points are
re-created.
- In the
Restore Files to box, click Original Location.
NOTE: When you choose to restore a file to an alternative location or to a
single file, not all system state data is restored. These options are used
mostly for boot files or registry keys.
- Click Start
Restore.
- After the restore
process is finished, restart the computer.
Caution
Using the Registry Editor incorrectly can cause data loss or even operating
system failure. Be careful when directly editing the registry.
