Data Availability refers to the accessibility of data when it is needed. It ensures that information is stored in a way that allows users to retrieve it quickly and efficiently. This is crucial for businesses and organizations that rely on timely data for decision-making and operations. To maintain Data Availability, systems often use backups, redundancy, and failover mechanisms. These strategies help prevent data loss and ensure that users can access the information they need, even in the event of hardware failures or other disruptions.
