Abstract: A logical number (LUN) cloning technique separates data blocks referenced by a writable virtual disk (vdisk) from data blocks referenced only by a backing store to conserve storage resources of a storage system. The LUN cloning technique separates the writable vdisk data blocks from the backing store during periods of reduced processing activity and in a manner that does not interfere with storage service provided by the system.

Abstract translation: 逻辑号（LUN）克隆技术将可写虚拟磁盘（vdisk）引用的数据块与仅由后备存储库引用的数据块进行分离，以节省存储系统的存储资源。 LUN克隆技术将可写虚拟磁盘数据块与后备存储区分离，在处理活动缩短期间以不影响系统提供的存储服务的方式进行。
