Backup, Restoration, and Continuity Architecture

Why this chapter matters

Continuity is the promise that a failure does not have to become an amnesia. This chapter treats backup, restoration, testing, and migration as governance work because a system that cannot recover its meaning cannot safely claim to preserve it.

Continue to Secrets and Key Custody Architecture to examine the materials that make recovery trustworthy.

Purpose

Defines vendor-neutral continuity, backup, restoration, custody, provenance, and failure evidence for protected Stygian records.

Normative clauses

  • INFRA-R001: Every backup shall identify source scope, creation time, digest, custody, classification, retention, and restoration dependencies.
  • INFRA-R002: Restoration tests shall verify readability, integrity, provenance, completeness, and applicability without treating a copy as a new authority source.
  • INFRA-R003: Continuity plans shall preserve P0, identity evidence, provenance, memory, and uncertainty across failure domains.
  • INFRA-R004: Failed, partial, stale, or conflicting restoration evidence shall block dependent use and preserve the failure record.
  • INFRA-R005: Backup access shall be least-privilege, auditable, reversible where possible, and separated from authority recognition.

Examples and exclusions

A restored archive may support continuity evidence while remaining Unknown until its digest and custody are verified. This Draft contains no vendor, endpoint, credential, production topology, or live restoration procedure.

Continuity record minimum

Each continuity exercise shall record scope, dependency map, backup digest, custody, restoration method, start and completion times, readability result, integrity result, missing material, limitations, and follow-up disposition. A successful technical restore does not by itself restore authority or identity.

Failure domains and review

Continuity planning shall consider loss, corruption, replay, isolation, unavailable custody, format drift, and conflicting copies. Failed or partial exercises preserve evidence and block claims of recoverability until reviewed. The sequence of continuity work may address constitutional text, identity evidence, provenance, memory, safety, and reversibility in that operational order, but this is only a preservation heuristic subordinate to P0 and the Constitution. It cannot reorder protected interests, create authority, or override a higher rule.

Archival media validation

  • INFRA-R006: An archival validation exercise shall identify source scope, format and medium class, digest, custody interval, retention and legal-hold state, restoration method, readability result, and limitations.
  • INFRA-R007: Validation shall distinguish readability, integrity, completeness, provenance, and applicability. A readable copy with an unverified digest or incomplete custody remains non-authoritative.
  • INFRA-R008: Format migration shall preserve source and target digests, transformation evidence, effective time, responsible actor, verification result, and rollback or supersession relationship.
  • INFRA-R009: Failed, partial, unreadable, altered, stale, or conflicting media evidence shall be retained and shall block dependent recoverability or deletion claims.
  • INFRA-R010: A continuity exercise may recommend preservation, retry, quarantine, or escalation, but it shall not create authority, recognise identity, or authorize destructive migration or production restoration.
  • INFRA-R011: Continuity design SHALL identify recovery objectives, dependency order, privacy and legal-hold limits, decision owner, and the smallest safe restoration claim.
  • INFRA-R012: Restoration SHALL distinguish technical availability from semantic continuity, authority, identity, completeness, and applicability.
  • INFRA-R013: Recovery exceptions SHALL be attributable, reversible where practicable, time-bounded, and subject to retrospective review.
  • INFRA-R014: This architecture SHALL NOT operate live backups, restore production systems, activate credentials, or transfer identity.

Design evidence

Continuity review should compare recovery objectives with dependency, custody, format, integrity, privacy, and legal-hold evidence. Exercises should preserve partial failure and identify the smallest safe restoration claim rather than reporting a binary success.

Operating model and evidence

Continuity planning compares protected records, dependencies, failure domains, recovery objectives, custody, format, integrity, privacy, legal hold, and restoration authority. It identifies what can be restored safely, what remains unknown, and which records or powers must remain frozen until verification completes. A technically readable copy can support preservation without becoming authoritative.

Reviewers test loss, corruption, replay, isolation, unavailable custody, format drift, conflicting copies, partial restoration, and recovery coercion. Each exercise records owner, evidence, limitations, retry or quarantine path, and restoration or supersession decision. Recovery remains subordinate to constitutional limits and review.

Interpretation cases

  • Conforming: Recovery objectives, dependencies, custody, integrity, privacy, legal hold, restoration, and limitations are recorded.
  • Prohibited: A successful restore creates identity, authority, or permission.
  • Boundary: A partial restore supports only the smallest verified preservation claim.
  • Failure: Conflicting or stale copies cause quarantine, pause, and evidence retention.
  • Loophole: Emergency restoration bypasses review or destructive-change safeguards.
  • Misuse: Continuity records expose credentials, private identity, or sensitive topology.
  • Care-control: Restoration protects people and memory while preserving choice, privacy, and review.
