Database High Availability is a critical aspect of modern data management, ensuring that databases remain accessible and reliable even in the face of unexpected events or system failures. Database High Availability enables organizations to maintain continuous operations, protect their data from loss or corruption, and meet strict service-level agreements (SLAs).

Database High Availability Terminology

To understand Database High Availability, it is important to know a few key terms:

  • Failover: The process of automatically switching to a backup system or database when the primary system or database experiences a failure.
  • Recovery Point Objective (RPO): The maximum amount of data that can be lost during a system failure. It determines how often data is backed up.
  • Recovery Time Objective (RTO): The maximum amount of time that a system can be unavailable due to a failure. It measures the efficiency of the failover process.
