Data Immutability and Retention Locking: Understanding WORM Storage Implementation

Explore a comprehensive 50-minute conference presentation from the Storage Developer Conference (SDC) 2023 that delves into data immutability and retention locking/WORM technologies in backup systems. Learn about the critical importance of these technologies in combating cyber and ransomware attacks, while understanding regulatory requirements for long-term data retention. Master the concepts of retention locking variants, dual authorization models, security officer roles, and various retention locking attributes. Discover how backup applications integrate with retention locking systems and their implementation in replication and cloud storage environments. Examine the challenges in achieving complete data immutability across multiple layers including operating systems, hypervisors, bootloaders, BIOS, server management interfaces, and physical datacenter access, along with their potential solutions. Understand how appliance form-factors of backup systems, shared-responsibility models, and air-gapped vaults contribute to enhanced data protection. Presented by Dell Technologies experts Sailu Yallapragada and Jagannathdas Rath, gain valuable insights into the ecosystem-wide adoption of data immutability and its practical applications in modern data protection strategies.
