Implements ransomware-resistant backups using restic with S3-compatible Object Lock (AWS S3, MinIO, Backblaze B2), automating backup creation, integrity checks via restic check --read-data, retention enforcement, and restore testing. Use when building immutable backup infrastructure, adding a WORM copy to a 3-2-1-1-0 strategy, or automating scheduled backup-verification workflows.

# Implementing Immutable Backup with Restic
## When to Use
- Establishing ransomware-resistant backup infrastructure with cryptographic integrity verification
- Implementing 3-2-1-1-0 backup strategy where the extra 1 is an immutable copy
- Automating backup verification workflows that test restore capability on a schedule
- Protecting backup repositories from deletion or modification by compromised admin accounts
- Meeting compliance requirements for data retention with tamper-proof storage
**Do not use** as the sole backup solution without also maintaining offline/air-gapped copies. Object lock protects against logical deletion but not physical storage failure.
## Prerequisites
- restic binary installed (https://restic.readthedocs.io/)
