Backup of Lightweight Directory Services with NTDSutil and dsdbutil

Taking Active Directory manual backup using NTDSutil and DSDButil is straightforward. First we will see how to take backup of Active directory using NTDSutil.

Backup of Active Directory using NTDSutil:

We will find out how to take backup of active directory database and logs, before taking backup using NTDSutil first you need to stop the Lightweight Directory instance that we have created in previous post Installation of AD LDS. Run the command prompt as administrator and run the following command for stopping the Lightweight Directory instance named “LDS-ins”.

C:UsersAdministrator>net stop LDS-ins

Also I have created a backup folder for backup in my C drive which have following three sub folders.

c:backupdata                                 For LDS data files

c:backupLDSbackup                    For LDS backup

c:backuplogs                                  For LDS logs

Now use the command ntdsutil for open ntdsutil console, and run the command activate instance LDS-ins where LDS-ins is LDS instance. Now type the “file” and press enter and run the command “move db to E:backupdata” to move database to data folder.

C:UsersAdministrator>net stop LDS-ins
C:UsersAdministrator>ntdsutilntdsutil: activate instance LDS-insntdsutil:file

file maintenance: move db to c:backupdata

DSDButil is preferred tool for working with LDS, you can open dsdbutil-tool by running command dsbdutil in command prompt, make sure you run the administrator’s command prompt. And for backup also review the following commands:


dsdbutil: activate instance LDS-INS

Active instance set to "LDS-INS".
