How Host Duplication Works

The host duplication facility enables you to copy all the data on the host server and transfer it to another. This feature is useful when:

You are upgrading your server and you want to move your data to a new system without shutting it down for hardware migration.
You want to maintain a duplicate server as a backup in case your current system fails.

The following diagram illustrates the process of host duplication:

Note: As a best practice, you should reset the host duplication parameter after the job is complete.

To enable this feature, set the original host parameter in util_par_file to the name of the host from which the data being backed up originated.

Note: For more information about configuring these variables, see Installing and Configuring the Option.
