Hardware replacement during disaster recovery

Last published : Apr 02, 2026
You can use Simplified Disaster Recovery (SDR) to recover a computer that is no longer functioning. For example, if the computer's main system board fails, you can restore the computer's data after you replace the system board. You can also restore the data even if the new board is a different model or if it contains multiple processors.
If you plan to change the hardware in the computer being recovered, consider the following information before you use SDR to recover the computer:

Item Description
Hard drives Any hard drives that you replace should be the same size or larger than the original drives.
System boards After you replace a faulty system board and after you use SDR to recover the computer, you must use the system board manufacturer's driver CD to re-install additional functionality such as onboard sound and video.
Network interface cards If you change the network interface card in the computer that you want to recover, you must install the necessary network drivers. Without the network drivers, you cannot access the network if you want to use a remote Backup Exec server or remote legacy backup-to-disk folders to recover the computer. After you complete the recovery, you must install new network interface card drivers that match the network card that is currently in the computer.
In most instances, it is not necessary to install the drivers manually. Most drivers are available on the Simplified Disaster Recovery disk image. When you create the Simplified Disaster Recovery disk image, you can customize it to include any drivers that you may need.
