Why a Layered Storage Architecture is Critical for Cyber Resilience
summary
Argues that recovery depends on concrete layers: production snapshots (immutable or indelible), replicated copies, an S3 object backup tier, and a secure isolated recovery environment (SIRE) that holds validated data and forensic tooling. Claims snapshots speed restores but are not backups, recommends S3 for backup targets, advises SIRE for the top ~10 critical apps, and shows orchestration between layers and cloud lowers mean time to clean recover while preventing reinfection.
