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.
