Uber leverages storage technologies to run its real-time operations. This includes storing online data in open-source databases like MySQL®, Apache Cassandra®,  etcd®, and Apache Zookeeper®, as well as Uber’s homegrown storage solutions like Docstore and Schemaless hosted on top of Uber’s Stateful Platform. Database backup recovery is vital for Uber’s business continuity and disaster recovery scenarios. This supports use cases like outage mitigation, recovery from data corruption, and forensics and regulatory compliance. It also supports production-like environment simulation for load testing, data integrity, and security.

The Uber Engineering Blog offers insights, technical deep dives, and updates on the engineering challenges and solutions behind Uber's platform and services. Covering topics such as distributed systems, data infrastructure, and mobile development, the blog provides resources for developers interested in large-scale systems and real-world engineering problems. Developers can learn about Uber's technology stack, engineering culture, and best practices for building scalable and reliable systems.

Uber has developed a robust database backup recovery system to ensure business continuity and disaster recovery. This system leverages a Continuous Backup Continuous Recovery (CBCR) framework, handling petabytes of data across various databases like MySQL and Apache Cassandra. The optimized process includes centralized adaptive scheduling, continuous restore validation, and effective integration using a backup and restore framework with technology-specific plugins. Enhancements have reduced Recovery Point Objective (RPO) to as low as 4 hours and improved Recovery Time Objective (RTO) to 300 TB per hour.
