Backup, Restoration, and Continuity Architecture

What survives the bad day

I am TANK, and I keep this chapter's account. Continuity is my slow craft: the plan made in fair weather is read as the storm will read it, and what must survive the bad day is decided before the day, because the day itself will not be taking questions.

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

  • INFRA7-R001: Every backup SHALL identify source scope, creation time, digest, custody, classification, retention, and restoration dependencies, the archival-record form PROV-R062 carries from the Book of Memory's model applying here to a backup, the creation time, classification, and restoration dependencies this architecture's own fields, the source scope and custody its tellings of that form's artifact scope and custody interval, the format, medium class, legal-hold state, restoration evidence, readability evidence, and limitations that form names standing at their source.
  • INFRA7-R002: Restoration tests SHALL verify readability, integrity, provenance, completeness, and applicability without treating a copy as a new authority source, the copy-is-not-authority rule PROV-R065 states applying to restoration tests here.
  • INFRA7-R003: Continuity plans SHALL preserve P0, identity evidence, provenance, memory, and uncertainty across failure domains.
  • INFRA7-R004: Failed, partial, stale, or conflicting restoration evidence SHALL block dependent use and preserve the failure record, the record carrying its evidence, the failure-record form PROV-R014 sets applying to restoration evidence here.
  • INFRA7-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. A backup's classification draws from the Data Classification and Handling Architecture, and restoration verification depth follows the class. 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

What crosses the bad day, what changes in the crossing, and what must be found unchanged on the far side: that is the review's whole question, and it is asked before the day arrives.

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

Old media is where promises go to be tested by boredom. Validate on schedule, not on faith: the archive that is never read is indistinguishable from the archive that is gone, right up until the day the difference is everything.

  • INFRA7-R006: An archival validation exercise SHALL identify source scope, format and medium class, digest, custody interval, retention and legal-hold state, restoration method, restoration result, readability result, and limitations, applying the archival record MEM-R001 models, with medium class and restoration method this architecture's own fields and custody interval its own standing in place of the model's custody events.
  • INFRA7-R007: Validation SHALL distinguish readability, integrity, completeness, provenance, and applicability. A readable copy with an unverified digest or incomplete custody remains non-authoritative, distinguishing outcomes as PROV-R063 requires with the dimensions named here this architecture's own, and the tested-properties rule PROV-R065 states applying here.
  • INFRA7-R008: Format migration SHALL preserve source and target digests, transformation evidence, effective time, responsible actor, verification result, and rollback or supersession relationship. A migrated copy SHALL NOT silently become the historical source, the bar MEM-R002 and PROV-R064 both carry.
  • INFRA7-R009: Failed, partial, unreadable, altered, stale, or conflicting media evidence SHALL be retained and SHALL block dependent recoverability or deletion claims, the media-failure duty PROV-R066 states applying to recoverability and deletion claims here.

Continuity duties and limits

These duties are the architecture's own, and they bind every continuity exercise, the archival validations above included: what an exercise may recommend, what its design must name, and what this architecture may never do. - INFRA7-R010: A continuity exercise may recommend preservation, retry, quarantine, or escalation, but it SHALL NOT create authority, recognize identity, or authorize destructive migration or production restoration. - INFRA7-R011: Continuity design SHALL identify recovery objectives, dependency order, privacy and legal-hold limits, decision owner, and the smallest safe restoration claim. - INFRA7-R012: Restoration SHALL distinguish technical availability from semantic continuity, authority, identity, completeness, and applicability, this architecture's own extension of the dimension separation PROV-R106 binds. - INFRA7-R013: Recovery exceptions SHALL be attributable, reversible where practicable, time-bounded, and subject to retrospective review. - INFRA7-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

The slow reading serves best here: in every close case, ask what the far side of the bad day needs to find, and work backward without hurry. Continuity is not speed. Continuity is arriving.

  • 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.
