Abstract: A system and method for providing a substantially constant-time copy operation for file system objects managed by a storage server begins by generating a snapshot of at least a portion of a data set managed by the storage server. The system then performs a copy operation in the storage server to generate a copy of the data set separate from the snapshot, on a set of block locations containing a predetermined reference value. During the copy operation to generate the copy of the data set separate from the snapshot, the system can receive from a requester a first read request directed to the copy of the data set that the copy operation is to generate. In response to the first data request, the system provides data from the snapshot to the requester by the storage server.

Abstract translation: 用于为由存储服务器管理的文件系统对象提供基本上恒定的复制操作的系统和方法开始于生成由存储服务器管理的数据集的至少一部分的快照。 然后，系统在存储服务器中执行复制操作，以在包含预定参考值的一组块位置上生成与快照分离的数据集的副本。 在复制操作期间，生成与快照分开的数据集的副本，系统可以从请求者接收针对复制操作要生成的数据集的副本的第一读请求。 响应于第一个数据请求，系统通过存储服务器将快照中的数据提供给请求者。
