摘要： A destination storage server, which may be a filer, mirrors a volume managed by a source storage server, which may also be a filer. According to an embodiment of the invention, changes made to the source volume are logged and persistently stored on a data container, such as a file, on the destination volume. The source storage server is coupled to clients that make data access requests to the volume. When an access request is made by a client, the request is written to a log on the source storage server. At the same time, the request is written to a data container on a volume managed by the destination storage server. Each source storage server coupled to the destination storage server has its own file on the volume.

摘要翻译： 可以是文件管理器的目标存储服务器镜像由源存储服务器（也可以是文件管理器）管理的卷。 根据本发明的实施例，对源卷的变化被记录并持久地存储在目的地卷上的数据容器（诸如文件）上。 源存储服务器耦合到使数据访问请求到卷的客户端。 当客户端进行访问请求时，将请求写入源存储服务器上的日志。 同时，请求被写入由目标存储服务器管理的卷上的数据容器。 耦合到目标存储服务器的每个源存储服务器在卷上都有自己的文件。
