Database downtime can have a devastating impact on any running service. Database backups are generally made robust with high availability by replicating them in a new server. However, storing a database backup on a new server is not cost-effective. At the same time, storing the backup in the same server does not ensure high availability. In this paper, we propose creating a secure database backup architecture using a transaction blockchain and peer-to-peer network to record the history of the transactions. Our architecture makes database backups highly available with a 4 percent decrease in throughput. © 2021 IEEE.BlockchainDatabaseIPFSPeer-to-peer network
