Abstract: A system and method for improving the efficiency of the transmission of updated blocks generated by logging all the block allocations and deletes as well as CPs and PCPI creation and deletion in a persistent log. The log is scanned during each update cycle (in which changes are transmitted to a destination mirror) by the storage operating system, and only changed blocks that are referenced by the file system as it existed at the end of the update cycle or referenced by PCPIs that existed at the end of the update cycle are actually sent in the transmission. This reduces the number of changes being transmitted.
Abstract translation: 通过在持久性日志中记录所有块分配和删除以及CP和PCPI创建和删除而生成的更新块的传输效率的系统和方法。 在存储操作系统的每个更新周期（其中更改被传送到目标镜像）的每个更新周期中扫描日志，并且仅更改文件系统引用的块，因为它在更新周期结束时存在或由PCPI引用 在更新周期结束时存在的数据实际上是在传输中发送的。 这减少了正在发送的更改的数量。
