DHCP Backup and Restore

  • Article

Applies To: Windows Server 2008

Maintaining a backup of the Dynamic Host Configuration Protocol (DHCP) database protects you from data loss in the event of data corruption or a hard disk failure.

There are three backup methods supported by the DHCP Server service:

  • Synchronous backups that occur automatically. The default backup interval is 60 minutes.
  • Asynchronous (manual) backups, performed by using the Backup command in the DHCP snap-in.
  • Backups using Windows Backup (Ntbackup.exe) or other backup software.

When a synchronous or asynchronous backup occurs, the entire DHCP database is saved.
