    or do i have to perform backup for dhcp separately?
    btw my domain controllers are the DHCP servers.


    Yes you have to backup your DHCP seperately. Listed below is the Procedure


    1. Open DHCP.
    2. In the console tree, click the applicable DHCP server.
    3. On the Action menu, click Backup.
    4. In the Browse For Folder dialog box, select the folder where you want to store the backup DHCP database, and then click OK.

  • Hi,

    Syed is right. DHCP database is not a part of the system state. You may need to backup them sepeartely. Moreover, since the Windows Server Backup is based on the VSS technology to backup system state, if there is an writer on the system, it should be backup.

    You may run the command to check if there is a DHCP writer on the DC

    vssadmin list writers

    Hope this can be helpful.

    Thanks and regards,

  • Hi,

    I am a little confused. I asked this question on Windows Server Backup forum and someone over there said that the DHCP data is a part of System State. Here's the link:


    Could some one please point me to an official article where it's mentioned whether DHCP data is a part of system state or not?

    Regards
