Data redundancy plays a critical role in architectural resilience because it provides a backup mechanism for data in case of a failure or problem in the primary system. By duplicating data across multiple systems or locations, redundancy ensures that if one system fails, data can still be accessed and the system can continue to function. This redundancy can help prevent system downtime, data loss, or other disruptions to operations, which can be critical for businesses or organizations that rely heavily on technology. Additionally, having multiple copies of data can provide protection against cyber attacks or malicious actions, as it becomes more difficult for attackers to compromise all copies of the data simultaneously.
