US07-05 — Deliver Backup and Operational Recovery

Epic: E07

As an operator, I want documented and tested backup/recovery procedures so application
state can be restored after migration failure, database damage, or storage loss.

Acceptance criteria

  • Online backup includes database consistency, required manifests, configuration
    references, and retention guidance without copying secrets into logs.
  • Integrity checks, migration rollback/recovery, archive media handling, and restore
    drills have step-by-step documentation.
  • Operational diagnostics report DB/WAL/cache/log/thumbnail sizes and low-disk risks.
  • Legacy-process locking prevents incompatible simultaneous mutations.

Automated tests

  • Recovery drills restore backups into fresh roots and run integrity/reconciliation.
  • Tests cover failed migration, corrupt copy detection, retention, and process locking.

Dependencies

  • US07-01, US07-04
