Use code from

http://poshcode.org/4017


Discovers DHCP online servers and if SystemRoot\Windows\System32\DHCP\Backup exists, copies the folder on each server to a network share (\\network\share\hostname).

Accepts two parameters:
SearchBase – Location of domain’s configuration container.
BackupDestRoot – Base folder where a folder for each host will be created to contain the copied DHCP database backups

Usage:
.\Backup-DhcpServers.ps1 -SearchBase “cn=configuration,dc=domain,dc=com” -BackupDestRoot “\\network\share\”

Two functions:
Get-OnlineDhcpServers
Backup-DhcpServers

No comment-based help.
No logging.
No error handling.

Known Issues:
BackupDestRoot parameter MUST end with a backslash (\). The script will eventually add a DHCP server’s hostname to this path to create that server’s backup destination.

If you do not use server 2012 then you cannot use the new DHCP cmdlets. However the script center has created a nice easy script that will export DHCP config for your servers. Take a look at the below link where you can download this from the Microsoft Script Center.

Export DHCP Settings (Microsoft Script Center)
