Which data protection mechanism helps ensure that data is accessible even in the event of a system failure?

Data backup solutions are crucial for ensuring that data remains accessible even during a system failure. These solutions involve creating copies of data that can be stored in different locations, ensuring that if the original data becomes inaccessible due to hardware failure, accidental deletion, or cyber incidents, a backup version can be restored quickly. This process is essential for business continuity, as it minimizes downtime and data loss, allowing organizations to resume operations with minimal disruption.

On the other hand, network security protocols, encryption algorithms, and access control lists address different aspects of data protection. Network security protocols focus on securing data in transit, ensuring safe communications over networks. Encryption algorithms are designed to protect data confidentiality by transforming data into a format that is unreadable without the correct decryption key. Access control lists manage who can access specific resources and data but do not provide recovery capabilities in case of failure.
