Techsplainers by IBM

This episode of Techsplainers explores immutable backups and why they are a core part of modern data protection. It explains how immutable backups create read-only copies of data that cannot be altered or deleted during a defined retention period, helping organizations defend against ransomware, accidental deletion, corruption and insider threats.
The episode walks through the difference between traditional backups, immutable backups and immutable snapshots, showing how each fits into a layered recovery strategy. It also examines the technical building blocks behind immutable backups, including WORM storage, retention locks, partitioning, air gapping, continuous data protection, encryption, access controls and AI-based threat detection.

Along the way, the discussion highlights the growing role immutable backups play in cyber resilience, disaster recovery and compliance across industries such as healthcare, finance and education. Listeners will also hear practical guidance on deployment choices, backup types, regular testing and integration with broader security operations. The result is a clear look at how immutable backups help organizations preserve data integrity and maintain reliable recovery options when systems are under attack.

This episode of Techsplainers explores immutable snapshots and why they are becoming an important part of modern infrastructure and cyber resilience strategies. It explains immutable snapshots as read-only, point-in-time copies of data that cannot be changed during their retention period, making them useful against malware, insider threats and accidental deletion.
The episode walks through how immutable snapshots differ from immutable backups, why snapshots often provide more granular recovery points, and how supporting technologies such as WORM, copy-on-write, retention policies, metadata and management APIs work together to preserve clean restore points.

It also looks at the financial and operational impact of breaches across hybrid environments, where data protection has become more complex and more costly. Along the way, listeners hear how immutable snapshots support disaster recovery, cyber recovery, data integrity, compliance and digital forensics.

The discussion also covers real-world use cases in regulated industries and best practices for aligning snapshot policies with business recovery goals.

This episode of Techsplainers explores unified storage and how it brings file, block and object storage together under a single platform. It walks listeners through the core idea behind unified storage, then explains how each storage type works, where each one fits best and why most enterprise environments need more than one approach at the same time.
The episode follows the operational challenges that arise when these storage types are managed in separate silos, including wasted capacity, added administrative overhead and fragmented visibility. It then examines the practical benefits of unification, from better capacity allocation and deduplication efficiency to simpler management and support for hybrid cloud and multicloud environments.

Along the way, the discussion also covers the tradeoffs. Unified storage can involve up-front migration costs, potential vendor lock-in, performance considerations for mixed workloads and the risk of creating a broader single point of failure. By the end, listeners get a clear view of where unified storage fits, where it may be unnecessary and why it can be a useful approach for organizations balancing flexibility, efficiency and scale.

This episode of Techsplainers explores network attached storage, or NAS, and explains why this long-standing storage approach still matters in modern infrastructure strategies. It walks through how NAS provides centralized file storage over a local network, making it easier for teams to share files, manage backups and maintain control over data.
The episode follows NAS from the basics to the bigger picture, covering core components like HDDs, SSDs, controllers, operating systems and file-sharing protocols. It also explains the difference between scale-up and scale-out NAS, and compares enterprise NAS with smaller business or consumer setups. Along the way, clear comparisons between NAS, DAS and SAN architectures.

The discussion also looks at where NAS fits today, including cloud integration, edge use cases and support for some AI workflows. Finally, it addresses the tradeoffs, the benefits, and the real-world use cases that keep NAS relevant.

This episode of Techsplainers explores what data storage is and why it remains a foundational part of modern computing. It explains how storage differs from memory, how computers retain data over time, and why the growth of AI and IoT systems is increasing pressure on storage systems to scale efficiently.
The episode walks through the main types of data storage: file, block and object storage, showing where each fits best in real-world environments. It also examines major storage architectures, including direct-attached storage, network-attached storage and storage area networks, highlighting the tradeoffs between simplicity, performance, cost and scalability.

From SSDs and flash to cloud, hybrid cloud, AI and edge storage, the discussion follows how storage technologies are evolving to support new workloads. It also covers the growing role of storage in cybersecurity and compliance, including encryption, immutable snapshots, cyber resilience and recovery testing requirements in regulated industries. Finally, it introduces software-defined, virtualized and intelligent storage approaches that help organizations manage data more efficiently at scale.
