HFS Plus의 적합성
Time Machine은 대부분의 경우 HFS Plus를 사용해야하지만 파일 시스템이 작업에 적합하지 않다는 점은 주목할 가치가 있습니다.
예
우연의 일치 :이 답변의 첫 번째 판이 나온 후 몇 시간이 지나면 내 Time Machine 백업 볼륨 (드문 드문 번들 디스크 이미지)에 파일 시스템 오류가 발생했습니다. 기본 스토리지가 정상이라고 확신합니다. HFS Plus 실패 전후에 ZFS 풀이 오류없이 제거되었습니다. 기록을 위해 :

간단히 말해서
솔루션을 원하지만 다음과 같은 파일 시스템 오류는 다음과 같습니다.
- 예측할 수없는
- 피하기 어려운
- 때로는 돌이킬 수없는.
좋은 해결책이없는 경우 최선의 조언은 단일 Time Machine 백업에 의존하지 않는 것입니다. 결국 고장 나거나 수리 할 수없는 위험이 너무 높습니다.
실패의 정도
과거에는 때때로 fsck_hfs
(8) b-tree 파일을 다시 만들 도록 강요 했지만 성공은 제한되었지만 확실하지는 않았습니다. 파일 시스템이 괜찮은 것처럼 보이지만 (디스크 유틸리티 등에서) 더 이상 Time Machine 백업 또는 복원 목적으로 파일 시스템을 신뢰하지 않습니다.
가장 최근의 경우 (위의) 여러 응용 프로그램 (카탈로그 b- 트리의 다중 재 구축, 확장 된 속성 b- 트리의 재 구축 및 b- 트리 범위의 재 구축)은 검증 가능한 파일 시스템으로 이어지지 않았습니다. 이 시도에서 디버그 로그가 있으며 여기에서 요약하지 않습니다. 그들은 거대하다.
로컬로 연결된 디스크 (USB 2.0)으로, 수리 Time Machine 백업 볼륨을 시도 할 수 있습니다 매우 많은 시간이 소요. 무선 – AFP 이상 – 필요한 시간을 견딜 수없는 경우가 있습니다.
타임머신-문제 해결 – C13. "… Time Machine이 새 백업을 만들어야합니다." (James Pond)에는 많은 유용한 정보가 포함되어 있습니다. 본질적으로 :
… 백업은 디스크 유틸리티의 수정 기능 이상으로 손상되었습니다…
OS X에서 HFS Plus 파일 시스템에 문제가없는 것으로보고되면 디스크에 심각한 문제가있을 수 있습니다. OS X에서 감지 할 수없는 문제입니다.
손상이 두 번 이상 발생하면 다음과 같은 문제가있을 수 있습니다.
- NAS의 하드웨어, 펌웨어 및 / 또는 소프트웨어.
NAS는 어떤 제조사와 모델입니까?
NAS의 하드 디스크
NAS의 OS에서 디스크의 블록 무결성 을 확인할 수있는 경우 : 그렇게하십시오.
NAS의 OS에 해당 기능이없는 경우 테스트에 더 적합한 다른 OS로 하드웨어를 부팅하는 것이 좋습니다. 옵션에는 Ubuntu 및 일련의 badblocks가 포함될 수 있습니다 .
이 유형의 점검 :
- 시간이 많이 걸릴 것입니다; 그러나
- 디스크 상태가 여러 오류에 영향을 주는지 여부를 확인하는 데 도움이됩니다.
