Scenarios: Performing backups in a high-availability environment

Depending on your high availability-solution and your backup strategy, the method for backing up data can be different. However, there is a common set of tasks when you perform backup operations for systems in a high availability environment.

In several high availability-solutions, you have the capability of performing remote backups from the second copy of data that is stored on the backup system. Remote backups allow you to keep your production system operational, while the second system is backed up. Each of these scenarios provides examples of two high-availability solutions where backups are performed remotely on the backup system.

In the first scenario, remote backups are performed in a high availability solution that uses geographic mirroring technology. The second scenario shows how the FlashCopy® feature can be used in a high-availability environment that use IBM® System Storage® solutions, such as metro or global mirror.
