This skill details implementing a ransomware-resistant, immutable backup strategy using the restic tool. It leverages S3-compatible Object Lock (Compliance Mode) to ensure Write Once Read Many (WORM) storage, preventing deletion or modification by attackers. The process includes automated backup, cryptographic integrity verification (restic check), and scheduled restore testing, adhering to advanced security standards like 3-2-1-1-0.

This skill provides a comprehensive framework for simulating and testing disaster recovery plans against ransomware threats. It guides users through measuring Recovery Time Objective (RTO) and Recovery Point Objective (RPO), validating clean backup restores, and hardening security controls to ensure organizational resilience. It is designed for tabletop exercises and compliance auditing, not for active incident response.

This skill provides a comprehensive framework for validating backup reliability. It automates processes like cryptographic hash verification, running simulated restores to isolated environments, detecting silent data corruption (bit rot), and scanning for ransomware indicators. Use it before relying on backups during a major incident or ransomware attack to ensure data recoverability and compliance.

This guide details the architecture and implementation of a ransomware-resilient backup strategy, adhering to the extended 3-2-1-1-0 methodology. It covers critical steps including defining RPO/RTO, establishing immutable/air-gapped copies, isolating backup credentials from the production domain, and automating periodic restore testing. Use this framework to ensure business continuity against sophisticated cyberattacks.
