HFS Plus'ın uygunluğu
Time Machine, HFS Plus'ı çoğu şey için kullanmak zorunda olsa da , dosya sisteminin görev için ideal olmadığına dikkat çekmek önemlidir .
Bir örnek
Tesadüf: Bu cevabın ilk basımından birkaç saat sonra, kendi Time Machine Yedeklemeleri hacmim (seyrek bir paket diski görüntüsü) dosya sistemi arızası yaşadı. Altta yatan depolamanın tamam olduğuna eminim - HFS Plus hatasından önce ve sonra, hatasız bir ZFS havuzu temizlendi. Kayıt için:

Basit anlamda
Bir çözüm isterken, bunun gibi dosya sistemi arızaları şöyle görünür:
- öngörülemeyen
- kaçınılmaz
- bazen tamir edilemez.
İyi bir çözüm bulunmadığında, en iyi tavsiyem tek bir Time Machine yedeğine güvenmemek. Sonunda başarısızlık ve tamir edememe riski çok fazla.
Başarısızlık dereceleri
Geçmişte bazen fsck_hfs
(8) b-tree dosyalarını yeniden oluşturmaya zorladım … sınırlı bir başarı ile ama kesin olarak değil. Bir dosya sistemi tamam gibi gözükse de (Disk Yardımcı Programında ve benzerlerinde) Time Machine yedekleme veya geri yükleme amaçları için artık güvenmiyorum.
En son durumda (yukarıda) çoklu kuvvet uygulamaları (katalog b-ağacının çoklu yeniden yapılandırması, genişletilmiş özniteliklerin b-ağacı yeniden yapılandırılması ve b-ağacının uzantılarının yeniden yapılandırılması) doğrulanabilir bir dosya sistemine yol açmamıştır. Bu denemelerde hata ayıklama günlükleri var, burada özetlemeye başlamayacağım; çok büyükler.
Yerel olarak takılı disklerle (USB 2.0), Time Machine yedekleme birimlerini onarma girişimleri olağanüstü zaman alabilir . Kablosuz - AFP üzerinden - gereken süreyi dayanılmaz bulabilirsiniz .
Zaman Makinesi - Sorun Giderme - C13. “… Time Machine sizin için yeni bir yedekleme oluşturmalı.” (James Pond) çok faydalı bilgiler içeriyor. esasen:
… Yedekler, Disk Utility'nin düzeltme yeteneğinin ötesinde bozuldu…
OS X bir HFS Plus dosya sisteminin uygun göründüğünü bildirdiğinde , diskle ilgili önemli sorunlar olabilir - OS X'in algılayamadığı sorunlar.
Yolsuzluk bir kereden fazla gerçekleştiğinden, aşağıdakilerle ilgili bir sorun olabilir:
- NAS'ın donanım, bellenimi ve / veya yazılımı.
NAS nedir ve modeli?
NAS'ın sabit diskleri
NAS'ın işletim sistemi disklerindeki blokların bütünlüğünü doğrulamanıza izin veriyorsa : lütfen bunu yapın.
NAS'ın işletim sistemi bu yeterliliğe sahip değilse, donanımı test için daha uygun olan farklı bir işletim sistemi ile başlatmayı hedefleyin. Seçenekler arasında Ubuntu ve bir dizi engelleme olabilir .
Bu tip kontroller:
- zaman alıcı olacak; fakat
- Disklerin durumunun çoklu arızalara katkıda bulunup bulunmadığını belirlemenize yardımcı olacaktır.
