A. The DHCP database backs itself up automatically every 60 minutes to the %SystemRoot%System32DhcpBackupJet directory. This interval can be changed:

  1. Start the registry editor

  2. Move to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesDHCPServerParametersBackupInterval

  3. Double click on BackupInterval and set to the number of minutes you want the backup to be performed. Click OK

  4. Close the registry editor

  5. Stop and restart the DHCP server service (Start - Settings - Control Panel - Services - DHCP Server - Start and Stop)

You could backup the %SystemRoot%System32DhcpBackupJet directory if you wish.
