A certification authority (CA) is an important resource for any organization. Therefore, it is important to plan for potential problems, such as hard disk failure or database corruption, by backing up and restoring a CA regularly. A complete backup of a server will also provide backup for the CA installed on the server. However, you can also back up and restore just the CA. Also, for hardware that is several years old, some organizations might decide to move a CA to new hardware both to improve performance and to remove older hardware from service before a critical component failure occurs.
