Summary#
중단된 삭제 작업을 복구할 때 불완전하거나 모순된 기록을 먼저 복구 대상으로 취급하면 잘못된 메타데이터 변경이 일어날 수 있다. 복구 기록의 인과관계와 백업의 소유권·완전성을 보수적으로 확인한 다음에만 수정을 시작한다.
Problem#
삭제 복구 과정에서 순환된 저널을 거부하기 전에 선행 복구가 메타데이터를 바꿀 수 있었고, 공유 데이터 디렉터리의 불완전한 백업이 유효한 백업으로 분류될 위험이 있었다.
Solution#
저널의 인과 그래프와 전체 세대의 백업 증거를 변경 전에 검증하고, 삭제 경로의 캐시 보호도 함께 적용한다.
Failure Modes#
- 검증 실패 전에 발생한 부분 변경
- 불완전한 백업의 유효 백업 오인
- 삭제 후 캐시에 남는 오래된 상태
