在主站点上，应用程序工作负载现在可以针对此数据库运行，并且MetroMirror函数会自动将磁盘级别的更改镜像到目标站点。
On the primary site, an application workload can now run against the database, and the Metro mirror function automatically mirrors changes at the disk level to the target site.
而且，如果所需的文件没有位于被镜像的磁盘上，包括来自存储过程创建的二进制文件，那么必须将这些文件手动复制到目标站点。
Also, any required files that do not reside on the mirrored disks, including binary files from the creation of stored procedures, must be manually copied to the target site.
在这种模式下，写操作是在数据存储到本地磁盘并镜像到对等节点内存后被确认的。
In this mode, the Write operation is acknowledged after the data is stored on the local disk and mirrored to the peer node's memory.
逆转磁盘镜像的方向以便目标站点上的磁盘可被镜像到主站点上的磁盘，如清单15所示。
Reverse the disk-mirroring direction such that the disks on the target site are now being mirrored to disks on the primary site, as shown in Listing 15.
点对点远程复制(peer - to - peer remote copy,PPRC)是将磁盘从一个存储系统镜像到远程站点中的另一个磁盘的协议。
