About protecting against component failures
NetBackup comprises a number of different components, each of which has the potential to fail, and disrupt the backup or restore process.
Table: NetBackup protection against component failures lists the component level points of failure and the related protection method.
Table: NetBackup protection against component failures
Point of failure | Protection method |
---|---|

Storage device connections | See About protecting against storage device connection failures. |
Storage devices | |
Media availability | |
Master server | |
Media server | |

Figure: Single points of failure and protection methods illustrates various NetBackup components and the single points of failure. The single points of failure can be eliminated at each component level either by making the component highly available or by deploying multiple components for redundancy.
