👉 Backup computing refers to the process of maintaining redundant copies of data and systems to ensure data availability, integrity, and disaster recovery in the event of failures or catastrophic events. In this context, backup computing involves setting up secondary systems or data centers that mirror the primary infrastructure, allowing for seamless failover and minimizing downtime. These backup systems can be local or geographically dispersed, providing protection against various threats such as hardware malfunctions, natural disasters, cyberattacks, or human errors. By regularly backing up data and maintaining these redundant systems, organizations can safeguard their critical information and ensure business continuity even under adverse conditions.
