# Runbook - Backup and Restore (Stage 4)

## Backup
- Stop write-heavy operations (or enter maintenance window).
- Run backup script:
  - `powershell -ExecutionPolicy Bypass -File scripts/backup_data.ps1`
- Keep backup config (`values.yaml`, contracts, runbooks).

## Restore drill
1. Start clean environment
2. Re-apply deployment manifests
3. Restore snapshots:
   - `powershell -ExecutionPolicy Bypass -File scripts/restore_data.ps1 -BackupZip <zip-path>`
4. Validate smoke scenarios:
   - login
   - create interaction
   - KPI endpoint

## Acceptance
- RTO and data integrity documented in pilot protocol
