On the other hand, a partial installation might get your Backup server up and running more quickly, so you can concentrate on continuing the disaster recovery. Later, you can recover the remainder of your operating system files using Backup. You will especially save time if you have a large number of clients and devices on the network that need to be configured; it will take you time to find IP addresses, hostnames, and recreate configurations.
Furthermore, if you wait to recover the remainder of the operating system files with Backup, you will be assured that the server, clients, and devices will be reconfigured exactly as they were prior to the disaster.
If you choose to do a partial install, you need to perform the following tasks:
If necessary, select a domain for the system.
Install the basic operating system files and device driver software.
Make sure the system communicates properly over the network.
After you reinstall the operating system, whether you did a complete or partial installation, run the tar command to verify that the tape drive is functioning properly.
