Uber's new differential backup system for its distributed databases significantly reduced storage costs by up to 70%, addressing the challenges posed by MyRocks migration.
The migration to MyRocks left Uber's Storage Platform team struggling with lengthy backup completion times and rising storage costs, necessitating a new solution to streamline processes.
The differential backup system utilizes the immutable characteristics of MyRocks' SSTable files, maintaining a shared pool of files and efficiently managing storage during backups.
Through an innovative approach, Uber's differential backups only add new SSTable files and reuse existing files, greatly optimizing backup processes and enhancing efficiency.
