NTFS提供哪些可靠性保证? [英] What reliability guarantees are provided by NTFS?

问题描述

我想知道NTFS对存储在其上的数据提供什么样的可靠性?例如，假设我打开一个文件，附加到末尾，然后关闭它，并且在此操作期间电源随机关闭.我可以找到文件完全损坏吗?

I wonder what kind of reliability guarantees NTFS provides about the data stored on it? For example, suppose I'm opening a file, appending to the end, then closing it, and the power goes out at a random time during this operation. Could I find the file completely corrupted?

我之所以问是因为我刚刚进行了系统锁定，发现其中两个附加到文件中的文件完全清零了.也就是说，大小合适，但完全由零字节组成.我以为即使发生故障，这也不应该在NTFS上发生.

I'm asking because I just had a system lock-up and found two of the files that were being appended to completely zeroed out. That is, of the right size, but made entirely of the zero byte. I thought this isn't supposed to happen on NTFS, even when things fail.

推荐答案

NTFS是事务性文件系统，因此它保证完整性-但仅用于元数据(MFT)，而不能保证(文件)内容.

NTFS is a transactional file system, so it guarantees integrity - but only for the metadata (MFT), not the (file) content.
