This episode breaks down snapshot backup fundamentals, covering the key differences between traditional storage snapshots and cloud-based approaches. Curtis and Prasanna explain copy-on-write versus redirect-on-write methods, performance implications, and why some snapshot systems can degrade performance by up to 50%.
Learn about NetApp's redirect-on-write innovation, VMware's unique approach, and how AWS "snapshots" are actually more like traditional backups. The hosts discuss critical concepts like read-only snapshot properties, storage space management, and the importance of copying snapshots to create true backups that follow the 3-2-1 rule.
Whether you're managing traditional storage arrays or cloud infrastructure, this episode provides practical guidance on turning snapshots into effective backup strategies. Topics include performance optimization, immutable storage considerations, and real-world implementation challenges that every IT professional faces.
