An interesting side effect of the copy-on-write design is that all writes to the file system become sequential writes (because remapping is always occurring).
即写即拷设计的一个有趣的副作用是文件系统的所有写入都成为顺序写入(因为始终进行重新映射)。
Embedded within ZFS is an implementation of an important set of features such as snapshots, copy-on-write clones, continuous integrity checking, and data protection through RAID-Z.
ZFS内嵌入的是重要功能集(如快照、即写即拷克隆、连续完整性检查和通过RAID - Z的数据保护)的实现。
This is accomplished by having an exception list that is updated every time something changes between the LVs (formally known as CoW, Copy-on-Write).
快照由一个例外列表(exception list)来实现，每当LV之间出现差异时就会更新这个列表(正式的说法是CoW,Copy - on - Write)。
Copy-on-write is advantageous for a number of reasons (not only for some of the capabilities like the snapshots and clones that it enables).
即写即拷有利的原因有多个(不仅仅是因为它可以启用的快照和克隆等一些功能)。
