On Windows 2008 R2, how do I back up DHCP if the DHCP .mdb database is always busy?

I get this from my backup software.

  • C:\WINDOWS\system32\dhcp\dhcp.mdb : The process cannot access the
    file because it is being used by another process.
  • C:\WINDOWS\system32\dhcp\j50.log : The process cannot access the file because it is being used by another process.
  • C:\WINDOWS\system32\dhcp\j50tmp.log : The process cannot access the file because it is being used by another process.
  • C:\WINDOWS\system32\dhcp\tmp.edb : The process cannot access the file because it is being used by another process.

My questions:

  • Should I be doing a manual backup of DHCP via command line tools or maybe with MMC, Action, Backup before I run my backup?
  • Is the %SystemRoot%\System32\DHCP\Backup directory always kept up to date? (which does get backed up by backup software) I'm answering my own question but the registry key is set up for 3c, 60 minutes, I believe. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCPServer\Parameters\BackupInterva

This is not the included backup software for Windows. It is another product, but I have seen this with every backup software I've ever used.

    Does your backup software provide a way to backup the system state information? The system state includes a copy of the DHCP database.
