Howto - Backup DHCP Database

The DHCP database backs itself up automatically every 60 minutes to the %SystemRoot%\System32\Dhcp\Backup\Jet directory. This interval can be changed:

Start the registry editor
Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCPServer\Parameters\BackupInterval
Double click on BackupInterval and set to the number of minutes you want the backup to be performed. Click OK
Close the registry editor
Stop and restart the DHCP server service (Start - Settings - Control Panel - Services - DHCP Server - Start and Stop)

You could backup the %SystemRoot%\System32\Dhcp\Backup\Jet directory if you wish.
