An enterprise AI team discovered that its most valuable assets — months of fine-tuned model weights, curated training datasets, and vector indexes — sat outside every backup policy it had. Model registries were classified as build output, not production state. Vector index rebuild time had never been measured. And recovering the application without the model it depended on would restore a service that started and then didn’t work. UPC Cyber Vault extended immutable WORM protection and AI-driven restorability validation to the full AI estate — artefacts versioned, datasets retained under the same rules as their source records, recovery coordinated alongside the applications that bind to them.
