Chapter 5. High-Availability Solutions for mySAP.comBackup, Recovery, and Failover

Keeping an SAP system up and running, including quickly recovering from failures, is one of the most important investment protection measures IT management can take. Keeping the application available 24 hours a day, 7 days a week, is a task that requires investments in three areas: people and processes, technology and infrastructure solutions, and support.

When a mission-critical system is unavailable at the wrong time, it can become very costly, and in some cases, threaten the existence of the organization. The reasons a system becomes unavailable can include simple hardware-infrastructure failures, system performance or capacity problems, software technology failures, human errors, changes to the system (including upgrades), as well as human or natural disasters. Being prepared for them helps minimize their impact on business operations.
