Patent abstract
A logical unit 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.
