ReFS is designed to pick up where 07001 leave off. To protect its internal data structures,file system metadata,and,optionally,user data against corruption,ReFS calculates and stores checksums for the data and metadata. Each piece of information protected by the checksum is fed into a checksum algorithm,and the result is a number,the checksum; in ReFS’s case,the checksum is a 64-bit number. Checksum algorithms are designed such that a small change in the input causes a large change in the resulting checksum.
Every time ReFS reads file system metadata (or data that has opted in to the checksum protection) it will compute the checksum for the information it has read,and compare this against the stored value. If the two are in agreement then the data has been read correctly; if they aren’t,it hasn’t.
那么 – Linux / Unix有什么可比性的吗?对Windows来说真的只是ZFS吗?如果没有,它有何不同?
解决方法
当我第一次看到这个消息时,我立刻想到了ZFS,多年来,许多被ReFS称之为开创性的功能.
不要误解我的意思–Windows急需一个新的文件系统,这似乎正朝着正确的方向发展.
Is it really just ZFS for Windows?
不,不是真的.从表面上看,它们共享相似的功能集,但它们在架构上截然不同. ReFS基于NTFS,而ZFS(据我所知)是从头开始设计的,没有明显的文件系统祖先.
