"Data Redundancy and Backup using Raspberry Pi 4 and AWS Services" explores a practical solution for safeguarding data in personal and small-scale enterprise settings. In a world where data is increasingly vital, a cost-effective approach that combines the Raspberry Pi 4 computer and Amazon Web Services (AWS) cloud capabilities has been introduced.
Firstly, the importance of data backup and redundancy in mitigating data loss risks has been discussed. It underscores the vulnerabilities of relying solely on local storage and highlights the value of cloud-based backup. The technical details of the proposed system are then outlined. It is explained how the Raspberry Pi 4 can serve as a local data hub for automated data backups from connected devices, while AWS services act as the remote backup destination. The solution includes the setup of AWS S3 and Glacier, noting their scalability, security, and reliability in maintaining redundant data copies. Crucial system components, such as data encryption, data transfer protocols, and data versioning, are explained to ensure data security and integrity. Cost considerations are addressed with a cost-benefit analysis that illustrates the affordability of this solution compared to conventional backup methods.
Furthermore, the importance of using RAID on Raspberry Pi to maintain a local data redundancy solution has been discussed and has also been deployed and configured. The same RAID data is also backed up to AWS S3 buckets to make sure an extra layer of data integrity is added to the whole system.
