Beyond 3-2-1- Architecting Resilient Financial Data Pipelines
For enterprise financial institutions, data loss is not merely an operational inconvenience; it is an existential threat. The traditional 3-2-1 backup rule—keep three copies of data, on two different media types, with one offsite—has long been the gold standard for disaster recovery. However, in an era of sophisticated ransomware and stringent regulatory frameworks like Basel III, a basic implementation of this rule is no longer sufficient. To truly secure financial ledgers, transaction histories, and customer PII, IT architects must evolve the 3-2-1 backup methodology into a resilient, compliance-first data pipeline. This involves integrating immutability, advanced encryption, and AI-driven validation into the core backup strategy.

In high-frequency trading environments or core banking systems, speed is critical, but so is internal security. ...
