AWS Technical Essentials Practice

AWS ensures data protection in Glacier primarily through the use of encryption and data redundancy. Encryption is applied both at rest and in transit, meaning that the data is secured whether it is being stored or moving across networks. This ensures that unauthorized users cannot easily access or understand the stored data, thereby maintaining confidentiality.

Moreover, data redundancy is a key aspect of AWS’s architecture. When data is stored in Glacier, it is automatically replicated across multiple geographically isolated facilities. This redundancy protects data against loss due to hardware failures or other issues that might affect a single storage location. Such mechanisms enhance durability and availability, ensuring that data remains intact over time, even in the face of unexpected events.

The other approaches mentioned, such as manual backups, limiting access to administrators, and conducting regular audits, typically comprise part of comprehensive data management strategies but do not specifically address the inherent data protection features provided by Glacier itself. Therefore, the use of encryption and data redundancy stands out as the primary means of ensuring data protection in this storage solution.
